Abstract

The invention relates to an intelligent power module, a circuit board and an electrical device. The intelligent power module comprises a substrate, a main control circuit, an auxiliary control circuitand an inverter circuit, wherein the main control circuit, the auxiliary control circuit and the inverter circuit are arranged on the substrate to achieve the integration arrangement of the main control circuit, the auxiliary control circuit and the inverter circuit so that the PCB in the electronic control board does not need to reserve installation positions of the main control circuit and theauxiliary control circuit and the installation positions of components of an interface circuit between the main control circuit and the auxiliary control circuit, the occupied area of the PCB is reduced, the size of the electronic control board is reduced, the circuit length between the main control circuit and the auxiliary control circuit is shortened, the parasitic parameters and the noise arereduced, and the EMC test is easier. According to the technical scheme of the invention, the size of the electronic control board can be reduced, and the reliability of the electronic control board can be improved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an intelligent power module, a circuit board and electrical equipment. Background technique [0002] Intelligent Power Module, or IPM (Intelligent Power Module), is a power drive product that combines power electronics and integrated circuit technology. It is generally used on electric control boards that drive fans, compressors and other equipment. [0003] The existing intelligent power module needs to be separately equipped with a Microcontroller Unit (MCU) chip in the application circuit, so as to provide relevant pulse width modulation (Pulse WidthModulation, PWM) signals and detection signals and other control signals for it, and then make the intelligent power module The power module is running. [0004] However, the design method of the electric control board is realized by using the circuit mode of the MCU chip and the intelligent power module. When wiring t...
