IGBT based Boost Derived Hybrid Converter
The hybrid converter produces dc output as well as ac output from a single
dc input. This topology is realized by replacing the controlled switch of a
traditional single-switch boost converters with a voltage-source-inverter
bridge network. In order to obtain two outputs (both dc & ac) from a single
converter, the inverter switches are appropriately operated in the boost
mode as well as in the inverter mode. One of the outputs is taken from
Inverter Leg as AC o/p and other is from the boost converter leg as DC
output. The following are the specification of BDHC.
I/P DC Voltage - 80 Volt , O/P DC Voltage - 250 Volt , O/P DC Current
- 25 Amp,O/P AC Voltage - 50 Volt ,O/P AC Current - 15 Amp,
Switching Frequency - 100 kHz,Fundamental Frequency - 50 Hz
Type of Cooling:- Forced Air, Ambient Temp:- 40 Deg, Duty Class:- Class

I Cooling Method Forced Air Cooled.
(i) IGBT Details ,V-IGBT=4, Generation Trench V-IGBT, CAL4= Soft
switching 4 Generation CAL-diode.
Isolated copper base plate using DCB technology (Direct Copper Bonding).
Increased power cycling capability. With integrated gate resistor. Low
switching losses at high di/dt
(ii) Gate Driver ,It should interface and isolate the Control Unit/Primary
Circuit from the secondary which is directly connected to the high power.
Gate Driver controls the IGBT’s dynamic behavior and its short circuit
protection. Input signal level is 0/15V. Interlocking time between the input
signals is 3µs. It monitors the errors: power supply under-voltage (below 13
V), short-circuit between Collector and Emitter. The error reset time is
typically 9µs. On detection of error/fault, the Gate Driver switches off the
IGBT. The IGBT switching speed may be adjusted by the resistors RGON
and RGOFF. The two parameters (Rce, Cce) define the values and time
delays for the comparison of an internal reference with the monitored value
of Vce(sat).
