摘要
智能功率块内装驱动和保护电路,使产品设计更方便。VVVF变频器是一典型的应用实例。选用智能功率块时,要根据智能功率块过流动作电流来确定其峰值电流。在设计外围电路时,应设计相应的缓冲吸收电路,并根据需要设计规定的独立控制电源。
The built in driver and protection circuits of the intelligent
power modules (IPM) make the design easier The VVVF inverter is one of the typical examples of
the application of IPM When selecting IPM's, the peak current should be determined according to
its over current action current; when designing the peripheral circuits, it is necessary to design
the independent power supply for the controlling circuits (3 refs )
