示例性的，自举电路104可以是二极管+电阻的模式，也可以是MOS管+控制电路的模式，本发明对此不进行具体限定。
在一实施例中，由于实现电机驱动还需要PFC驱动模块，PFC驱动模块包括PFC驱动电路和PFC开关，而PFC开关属于大功率器件，不适合集成在高压集成电路中，PFC驱动电路功率不大，因此可以将PFC驱动电路集成到高压集成电路中，以减少智能功率模块中的器件数量，进而降低智能功率模块的布局和封装困难。
基于此，如上述图2所示，该高压集成电路还可包括PFC驱动电路和PFC控制输入端PFCIN；所述PFC控制输入端PFCIN与所述信号处理电路101的输入端连接，所述信号处理电路101的输出端还与所述PFC驱动电路105连接。

需要说明的是，由于风机的功率较低，可以将风机的功率逆变部分也集成到高压集成电路，以减少智能功率模块中的器件数量，进而降低智能功率模块的布局和封装困难，并降低智能功率模块内部的电磁干扰。而压缩机的功率较大，其对应的功率逆变部分不适合集成到高压集成电路中。
