Abstract

The invention provides an intelligent power module and an air conditioner controller. An adjustment circuit is additionally arranged between each driving circuit and a corresponding insulated gate bipolar transistor (IGBT) tube in the power intelligent module and can be used for detecting change of a power supply voltage value of a low-voltage region of the intelligent power module in real time and enabling the module to stop outputting when the voltage value caused by fluctuation of a low-voltage power supply is excessively low, so that charge accumulated by the IGBT tube in the module can be released when the charge of the IGBT tube in the module is accumulated caused by energy storage of a driving motor, the charge is continued to be safety, rapidly and completely released within an appropriate time selected by timing when the power supply voltage is restored to be normal, and the impact of the charge to a circuit in the module is prevented to affect working reliability.

Description

technical field [0001] The invention relates to the technical field of intelligent power modules, in particular to an intelligent power module and an air conditioner controller. 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 is equipped with fault detection circuits such as overvoltage, overcurrent and overheating inside. On the one hand, the intelligent power module receives the control signal from the MCU to drive the subsequent circuit to work, and on the other hand, it sends the system status detection signal back to the MCU. Intelligent power modules are especially suitable for frequency converters and various inverter power supplies for driving motors. They are ideal power electronic devices for frequency conversion speed regul...
