High Frequency Soft Switching Of PWM Boost Converter Using Auxiliary Resonant...IJERA Editor
This thesis presents High frequency Soft Switching DC-DC boost Converter. The circuit consists of a general Boost Converter with an additional resonant circuit which has a switch, inductor, capacitor and a diode.In general Boost Converter circuits have snubber circuits where switching losses are dissipated in external passive resistors; which is known as hard switching. As the switching frequency of PWM converters is increased its switching losses and conduction losses also increases. This restricts the use of PWM technique. New Zero Voltage Transition-Zero Current Transition (ZVT-ZCT) PWM converter equipped with the snubber provides the most desirable features of both ZVT and ZCT converters presented previously. Moreover all semiconductors devices operate with soft switching and hence losses are reduced.

Review of Step down Converter with Efficient ZVS OperationIJRST Journal
This paper presents the review of step down converter with efficient ZVS operation. The designed buck converter uses ZCS technique and the function is realized so that the power form is converted from 12V DC 5V DC (1A). A detailed analysis of zero current switching buck converters is performed and a mathematical analysis of the mode of operation is also presented. In order to reduce the switching losses in associated with conventional converters; resonant inductor and resonant capacitor (LC resonant circuit) is applied which helps to turn on-off the switch at zero current. The dc-dc buck converter receives the energy from the input source, when the switch is turned-on. The buck–buck converters have characteristics that warrant a more detailed study. The buck converters under discontinuous conduction mode /continuous conduction mode boundary.
NON-ISOLATED SOFT SWITCHING DC-DC CONVERTER AND LOAD AT FULL RANGE OF ZVS IAEME Publication
A non isolated soft switching DC–DC converter and load at full range of zero-voltage
switching (ZVS) characteristic is proposed. The proposed converter consists of an auxiliary circuit,
an inductor, two switches, and 2 diodes to achieving high efficiency at full range of load. At low
and heavy loads, ZVS of switching device is achieved by energy storing component. The inductor
energy stored varies with load and hence results in minimizes conduction loss. This leads to
switching of device for full range of load. The proposed DC - DC converter achieves high
efficiency as switching loss is reduced due to soft switching and ZVS operation which severe to
reduce conduction loss. The efficiency is improved about 4% in boost mode (2.5% in buck mode) at
full range of load. To verify the performance of the proposed converter, experimental results
prototype are presented.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Introduction to Boost converter
A Boost converter is a switch mode DC to DC converter in which the output voltage is greater
than the input voltage. It is also called as step up converter. The name step up converter comes
from the fact that analogous to step up transformer the input voltage is stepped up to a level
greater than the input voltage. By law of conservation of energy the input power has to be equal
to output power (assuming no losses in the circuit).
Input power (Pin) = output power (Pout)
SinceVin < Vout in a boost converter, it follows then that the output current is less than the input
current. Therefore in boost converter
Vin < Vout and Iin >Iout
Principle of operation of Boost converter
The main working principle of boost converter is that the inductor in the input circuit resists
sudden variations in input current. When switch is OFF the inductor stores energy in the form of
magnetic energy and discharges it when switch is closed. The capacitor in the output circuit is
assumed large enough that the time constant of RC circuit in the output stage is high. The large
time constant compared to switching period ensures a constant output voltage Vo(t) =
Vo(constant)

Modes of operation of Boost converter
The boost converter can be operated in two modes
a) Continuous conduction mode in which the current through inductor never goes to zero i.e.
inductor partially discharges before the start of the switching cycle.
b) Discontinuous conduction mode in which the current through inductor goes to zero i.e.
inductor is completely discharged at the end of switching cycle.
Circuit analysis of Boost converter
Assume in the entire analysis that the current swing (maximum to minimum value) through
inductor and voltage swing through capacitor is very less so that they vary in a linear fashion.
This is to ease the analysis and the results we will get through this analysis are quite accurate
compared to real values.
Continuous conduction mode
case-1: When switch S is ON
When switch in ON the diode will be open circuited since the n side of diode is at higher voltage
compared to p side which is shorted to ground through the switch. Hence the boost converter can
be redrawn as follows
During this state the inductor charges and the inductor current increases. The current through the
inductor is given as
5. 5
Assume that prior to the opening of switch the inductor current is I’L, off. Since the input voltage
is constant
Assume the switch is open for ton seconds which is given by D*Ts where D is duty cycle and Ts
is switching time period. The current through the inductor at the end of switch on state is given
as
(equation 1)
Hence ΔIL = (1/L)*Vin*D*Ts.
case 2: When switch is off
When switch in OFF the diode will be short circuited and the boost converter circuit can be
redrawn as follows
The inductor now discharges through the diode and RC combination. Assume that prior to the
closing of switch the inductor current is I’’L, off. The current through the inductor is given as
Note the negative sign signifies that the inductor is discharging. Assume the switch is open for
toff seconds which is given by (1-D)*Ts where D is duty cycle and Ts is switching time period.
The current through the inductor at the end of switch off state is given as
I’’’L, off = – (1/L) *(Vin-Vout)*(1-D)*Ts + I’’L, off (equation 2)
In steady state condition as the current through the inductor does not change abruptly, the current
at the end of switch on state and the current at the end of switch off state should be equal. Also
the currents at the start of switch off state should be equal to current at the end of switch on state.
Hence
I’’’L, off =IL, on, alsoI’’L, off =I’’L, off
Using the equations 1 and 2 we get
(1/L) *Vin*D*Ts = – (1/L) *(Vin-Vout)*(1-D)*Ts
Vin*D=- (Vin-Vout)*(1-D)
Vin* (D-1+D) = Vout*(1-D)
Vout/Vin = 1/ (1-D)
Since D < 1 Vout > Vin. Assuming no losses in the circuit and applying the law of conservation of
energy
Vout*Iout = Vin*Iin
This implies Iout/Iin = (1-D), Thus Iout < Iin. As the duty cycle increases the output voltage
increases and output current decreases. But due to parasitic elements in the lumped elements
resistor, inductor, capacitor the step up ratio Vout/Vin decreases at higher duty cycles and
approaches zero at unit duty cycle.
Discontinuous conduction mode
As mentioned before the converter when operated in discontinuous mode the inductor drains its
stored energy completely before completion of switching cycle. The current and voltage wave
forms of boost converter in discontinuous mode is shown in the figure below
The inductor in discontinuous mode drains all the current which it piled up in charging interval
of same switching cycle. The current through the inductor is given as
= (1/L )*

area under the curve of voltage v/s time. Hence from the wave forms shown in the
Vin*D*Ts = -(Vin-Vo)*δ*Ts(negative sign signifies that the inductor is discharging)
Vout/Vin =(D+ δ)/ δ
and the ratio of output to input current from law of conservation of energy is Iout/Iin =δ/ (D+ δ).
Applications of Boost converter
They are used in regulated DC power supplies.
They are used in regenerative braking of DC motors
Low power boost converters are used in portable device applications
As switching regulator circuit in highly efficient white LED drives
Boost converters are used in battery powered applications where there is space constraint
to stack more number of batteries in series to achieve higher voltages.
Conclusion:
In this practical we have perform simulation of boost converter using MATLAB SIMULINK &
conclude that in boost converter the output voltage is greater than the reference voltage.
