Abstract

The embodiment of the invention provides an intelligent power module and device. The intelligent power module comprises a plurality of power devices, a gate drive control circuit and a drive control circuit. The gate drive control circuit is used for carrying out physical over-temperature protection on each power device; the driving control circuit is used for driving each power device; the plurality of power devices comprise an upper bridge arm power device and a lower bridge arm power device. The intelligent power module also comprises a silicon carbide field effect transistor or a gallium nitride field effect transistor. The silicon carbide field effect transistor or the gallium nitride field effect transistor is arranged on a channel where the intelligent power module is connected witha corresponding power factor correction circuit. According to the embodiment of the invention, the technical problem of low IPM energy efficiency in the prior art is solved, and the beneficial effectof improving the energy efficiency of the IPM module is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of integrated circuits, and in particular to intelligent power modules and devices. Background technique [0002] IPM (Intelligent Power Module, Intelligent Power Module) is an advanced power switching device, which is essentially a module that integrates power devices and their drive control circuit chips; the IPM module plays an important role in the field of energy management that other integrated circuits cannot match. The performance of the device directly affects the utilization efficiency of the energy system. [0003] The IPM module in the prior art mainly includes two parts: an HVIC that plays a driving role and a power tube that plays a switching role. At present, for example, air conditioners account for 60% of the energy consumption of household appliances. If the air conditioners are replaced by inverter air conditioners, about 30% of energy consumption can be saved. The ...
