Abstract

The invention discloses an intelligent power module which comprises an HVIC tube and six IGBTs which are driven by the HVIC tube to be on or off. The HVIC tube is provided with six input ends and six output ends, the intelligent power module is provided with the adjustment end, the HVIC tube further comprises six delay adjustment units connected with the adjustment end, the adjustment end receives external adjustment signals to carry out delay adjustment on input signals to output the input signals to driving circuits, the driving circuits receive the input signals after the corresponding delay adjustment, and driving signals coincident with the corresponding input signals in delay are output through the output ends to the corresponding IGBTs. Due to the fact that the delay adjustment units are additionally arranged, it can be guaranteed that input-output initial delay of six channels is coincident, then the input-output delay of the six channels is uniformly controlled through adjustment signals to be increased or decreased, and therefore the intelligent power module has the certain universality for driving algorithms in different application environments.

Description

technical field [0001] The invention belongs to the field of integrated circuits, in particular to an intelligent power module. Background technique [0002] Intelligent Power Module, or IPM (Intelligent Power Module), is a power drive product that combines power electronics and integrated circuit technology. The intelligent power module integrates the power switching device and the high-voltage driving circuit, and has built-in fault detection circuits such as overvoltage, overcurrent and overheating. On the one hand, the intelligent power module receives the control signal of the MCU (Microprogrammed Control Unit, microprogram controller) to drive the subsequent circuit to work; on the other hand, it sends the system status detection signal back to the MCU. Compared with traditional discrete solutions, intelligent power modules have won an increasing market due to their advantages of high integration and high reliability. They are especially suitable for inverters and var...
