Interface, two six core connecting interfaces of ERIN, master driver can be connected by any one connecting interface with from driver.
It compares master driver from driver, including driving chip, resistor network, protection circuit, four core power interfaces, two
A six core connecting interface of ERIN.
Isolated power supply is exported by transformer secondary side, is directly connected to master driver or any one connects from drive power supply
Mouthful, principal and subordinate's driver is connected by parallel interface, realizes the transmission of power supply and driving signal.The light input interface of master driver is done
For the isolation input of entire driving device driving signal, driving signal is provided for device.
Principal and subordinate's driver is all directly fitted on IGBT, by auxiliary terminal G E C realize electrical connection and mechanical connection, subtract
Few driver the space occupied, provides basis for power module Miniaturization Design.
Isolated power supply is mountable to space of the power module close to IGBT, is also mountable to close to power module low-voltage signal
Input terminal, convenient and flexible installation is convenient for module overall planning, but if being installed to the space close to low-voltage terminal, needs to infuse
The insulating Design for the transformer secondary side and principal and subordinate's driving element harness of anticipating.
The parallel drive of four IGBT at most can be achieved in the utility model.The design of driving power is to can satisfy while driving
