2. Abstract
The HART Transverter is a Power Electronics converter which is able to convert and control
flow of power in any direction. It have in build rectifier, Inverter, chopper and AC voltage
regulator. It is able to convert AC grid power into DC to charge battery or DC of battery into
AC to supply Grid line. It also have function for solar, wind turbine and other renewable energy
sources.
This project contain HEART Transverter connection with five solar panel of 36V in parallel
and 24V battery bank which provides AC 116VAC 60Hz supply to light. This whole system
works standalone off gird. It don’t have any physical connection with Grid power supply.
HEART Transverter provides supply to light from solar panel when sun light is available and
also it keeps battery charged. When sun light is not available, battery starts supplying power to
bulb and Transverter converts DC supply into controlled AC.

8. 1 Introduction
HEART Transverter is a power electronics converter. It is able to convert and control the
amount and direction of power. This is controlled by separate controller which is connected to
transverter by standard Ethernet cable. Transverter contains following parts.
1. Controlled Rectifier
2. Inverter
3. DC to DC chopper
4. AC Voltage Regulator
1.1 Controlled rectifier
Controlled rectifier is a AC to DC converter which consist four SCR for 1-ɸ supply and six
SCR for 3-ɸ supply as shown in Figure 1. It provides DC power to charge battery from grid
power in Transverter. First it produce pulsating DC supply which is then filtered using proper
filters to get pure DC supply.
Figure 1 Controlled Rectifier

9. 1.2 Inverter
A power inverter, or inverter, is an electronic device or circuitry that changes direct current
(DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall
power handling depend on the design of the specific device or circuitry. The inverter does not
produce any power; the power is provided by the DC source.
As shown in Figure 2, four MOSFET‘s are triggered in pairs to produce AC supply at desired
frequency.
1.3 DC to DC Chopper
Figure 2 Single phase Inverter
Figure 3 DC to DC Chopper

10. A chopper is a switching device that converts fixed dc input to a variable dc output voltage
directly. Essentially, a chopper is an electronic switch that is used to interrupt one signal under
the control of another. Figure 3 shows typical chopper circuit.
1.4 AC Voltage Regulator
This is the latest technology of voltage regulation to provide real-time control of voltage
fluctuation, sag, and surge and also to control other power quality issues such as spikes &
EMI/RFI electrical noises. This uses an IGBT regulator engine generating PWM AC voltage
at high switching frequency. This AC PWM wave is superimposed on the main incoming wave
through a buck-boost transformer, to provide precisely regulated AC voltage. The regulation
in this technology is instantaneous, thus making it suitable for electronic machines which need
precise regulated power.

11. 2 HEART Transverter
HEART Transverter is shown in Figure 4. This Contains following parts to perform fully.
2.1 HT2000 Power Module
Figure 4 HEART Transverter
Figure 5 HT2000 Power Module

12. The HT2000 power module is a Universal Power Interface that, by using intense amounts of
logic, can bi-directionally transfer power between any combinations of its four connections.
Each power module has two DC connections and two AC connections. Each DC terminal can
connect to anything from 10-50 volts to things like batteries of any chemistry, solar panels, fuel
cells, DC wind generators, alternators, etc. The AC connections are for AC loads, the Grid and
generators. The power modules are 2 kW and as many as 12 can be connected together for up
to 24 kW. They have tremendous logic resources and create mathematical models of
everything connected to them. The Transverter system includes a remote panel, which reports
the condition of everything connected to the system and allows the user to control how power
is managed. The remote panel has a USB interface allowing for connection to any computer
for updates, custom configurations and in-depth live analysis of everything connected to it.
The Transverter can simultaneously be any combination of inverter, grid-tie inverter, UPS,
charge controller, DC-DC converter, programmable power supply or load bank, etc.

13. 2.2 HTREM Remote Panel
The HTREM remote panel gives all of the critical information at a glance on its four lines of
display. It has adjustable back lighting and four tri-color lads that indicate major conditions
and issues. It also has an audible alarm. Its waterproof sealed membrane panel has buttons for
simple user interface. The HTREM panel is required to operate both the HT2000 power
modules and the T13X smart load controller & power analyzer.
It also has a USB connection on both the front and back. Permanent installations use the back
USB connector and when a technician connects to the front USB connector it disables the back
USB and communicates only to the front USB.

14. 2.3 T13X Smart Grid Panel
The T13X completes the picture with everything else needed to implement the Smart Grid. It
has sense wires that connect to the main grid connections and either 100 amp or 250 amp split
core current transformers that clip on to the main grid wires coming into the building. It also
has six 30 amp relays that can be connected to some of the larger loads so that they can be
controlled by the intelligence of the system and provide demand response, load sharing and
automated reduction in power use when the system senses that no one is in the building. It has
4 connections for grid voltage and current measurement and so it can handle 3ф or 2ф and a
generator or some of these lines can be used to monitor large loads. Full oscilloscope
monitoring is provided for all phases of the grid as well as for all 6 relays for both voltage and
current. Also, 32 channels of data-logging are provided at samples rates from 1/sec to 16/min.
The current sensors for the relays can sense DC or AC and can detect unbalanced DC offsets
in the current. The T13X ties into the same data stream and communications for the remote
panel and the HT2000 power modules. This opens many new doors to applications like sensing
power factor, detecting when refrigerant has leaked from a refrigeration of air-conditioning
system or detecting the level of water and the amount of water consumed for a well. It, of
course, includes all features of any AMI system.

16. 3 Hardware Implementation
In this project five solar panels are connected in parallel which are connected at A port of DC
connectors on Transverter. Battery of 24 Volts are connected at B port of DC connectors on
Transverter. AC out is connected to extension cord which can supply to any AC device. Here
we used AC 60 watts bulb. Following photos shows hardware implementation of Transverter.

Fuse helps to limit battery current and it breaks the circuit when it cross the limit by melting
down itself. This safety devices are important in power connections.

Calibration of different voltage and current setting is important for correct function of
Transverter. Following table shows different values of calibration. This calibration is based on
24V battery. It don’t apply if there is 12V or 36V battery.

This project is related to power and sustainable energy sources. It helps to use solar energy in
residential houses which helps in saving non-conventional energy sources. It also helps in save
money on electricity bills. HEART Transverter is powerful enough to provide 2000 Watts
alone if there is solar power is available. It is future of smart grid connection which also
connects with micro-grids.
