PSHI_ACEE IGBT is an intelligent double channel(single channel) driver for generally IGBT which drives all IGBTs with V_CE up to 1200V and 1700V. With two pins interface,it also adopts high-integrated driving chip( PDI031、PDI032) 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 R _G and "soft turn-off" resistor R _GOFF-SC simply.By connecting subpanel PCB 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.
Optimized signal synchronization feature makes it is easiler to transform bewteen Serial and parallel.( Limited by the accuracy of the external device)

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 V_CE 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.

The driver installed with dedicated chips of high integration level cut down the number of logic devices by 80%，thus increasing the signal exchange velocity and enhancing the reliability of the system. Meanwhile，the increase in density cuts down the cost.

With a strong driving capability(the folling figure),and the high power output can be attained from more IGBTs.
