PSHI_PCB IGBT is an intelligent double channel(single channel) driver for generally IGBT which drives all IGBTs with VCE up to 1200V and 1700V. It adopts plug and play design .The adaption of the drivers to the application has been improved by using pins to change several parameters and functions. It can drive different IGBTs by adjusting their gate resistance RG and "soft turn-off" resistor RGOFF-SC simply.By connecting two indepedent 5 pins connector and IGBT,it can drive two IGBTs in half-bridge mode or indepedent mode.There is interlock function in half-bridge mode, and a dead time of TOP and BOT can be adjusted seperately.
The driver contains an input level selector (15V and 5V are compatible) to meet all outpt level from different control board.
The input stage drives set up Schmitt circuit contains a hysteresis up to 9V (select level 15V ) and it can eliminate all kinds of input noise effectively.
Interal 350ns (adjustable) narrow pulse restrain circuit to eliminate radio frequency interference.
All information that is transmitted between input and output uses ferrite transformers, resulting in high dv/dt immunity(50 kV/μs) which has high anti-jamming ability.
Short turn-off function is provided to protect IGBT from damage by high voltage spike. In case of short circuit, it automatically increases the IGBT turn-off time and hence reduces the VCE voltage overshoot to improve the IGBT's reliability which make it can be used in higher DC voltage application.This also means an increase in final output power.
Integrated DC/DC power supply with high galvanic isolation(4 kV/1 minute) ensures that the user is protected from the high voltage(secondary side). The power supply for the driver may be the same as used in the control board(+15V) without the requirement of isolation.
With a strong driving capability(the folling figure),and the high power output can be attained from more IGBT.
