1. A.Forward output : final year cse projects in Bangalore
The PWM signal of the main switch is given some delay compared to auxiliary switch. The
phase difference is obtained by delaying the carrier waveform. The main switch is turned on
while the auxiliary switch is still in the state. Before the main switch is turned on the anti-parallel
diode of the main switch is turned on. Final year eee projects in Bangalore. The main switch
voltage has a slope by the snubbed capacitor when the main switch turns off. The waveform
shows that the main switch operates at zero voltage condition.

around 380V. The average output current is obtained to be around38 A.

2. Reverse output
We then compared the torque outputs of without soft switching model and IGBT soft switching
model as shown in Fig. 7 and Fig. 8 respectively. Maximum torque in both models is 14 N-m. As
clear from the output, torque start decreasing in interval (0-0.01 sec) and after that it becomes
constant up to 0.22 sec and further decreases and becomes negative. Final year embedded
system projects in Chennai. After that it again starts increasing and becomes constant in
interval from 0.23 sec to 0.5 sec. From 0.5 sec it again starts increasing to maximum value and
after that it again decreases and become constant for the model without soft switching. Torque in
soft switching model decreasing in interval (0-0.01 sec) and after that it become constant up to
0.3 sec and further decreases and become negative. http://www.embeddedinnovationlab.com
After that it again starts increasing and becomes constant in interval from 0.3 sec to 0.5 sec.
From 0.5 sec it again starts increasing to maximum value and after that it again decreases and
become constant. http://www.embeddedinnovationlab.com.From the outputs we observed that
torque improves with soft switching technique. Finally, we compared the voltage outputs of
without soft switching model and IGBT soft switching model whose outputs are shown in Fig. 9
and Fig. 10.Voltage in without soft switching model decreases first and after that it becomes
constant. In soft switching model, voltage remains constant over the whole period. So we can
infer that there is no effect on the bus voltage when motor starts with soft switching.
The named as ‘isolated switched-capacitor tapped-inductor (SCTI) boost converter’. The
proposed converter consists of two parts. The primary side has a TI boost converter with a

an isolated charge pump. From the inductor tapping, the main switch voltage stress is
Reduced, final year mechanical projects in Chennai. And the voltage spike on the switch is
significantly attenuated. Given that low voltage stress exists on the active switch, the circuits can
use low voltage MOSFETs, which generally have low Rds(on). MOSFETs decrease the
conduction loss dramatically [10], thus making this variable one of the dominant factors of
efficiency. http://www.embeddedinnovationlab.com. The output of the switched cell is
connected with the boost output in series. The stacked-output structure of the proposed converter
is suitable for high-voltage and low-current applications. Compared with other multiple-module
connected topologies, MOSFET and diode are relieved from severe voltage stress. The DCM is
also employed to eliminate the reverse-recovery loss of the diode.
