Abstract

The invention provides an intelligent power module and an air conditioner. By adding an adjustment circuit between each internal drive circuit and the corresponding IGBT tube, the adjustment circuit can detect the change of the power supply voltage value in the low-voltage area of ​​the intelligent power module in real time. And when the low-voltage power supply fluctuates and causes the voltage value to be too low to stop the output of the module and cause the energy storage of the drive motor to cause the IGBT tube inside the module to accumulate charge, it can discharge the charge accumulated in the IGBT tube inside the module, and make the power supply When the voltage returns to normal operation, select an appropriate time by timing to continuously discharge the above-mentioned charges safely and quickly, so as to avoid the impact of the charges on the internal circuit of the module and affect the reliability of its work.

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. 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 regulation, meta...
