WebPTC Thermistors aid in preventing severe damage to link capacitors, IGBTs, and preventing blown fuses and tripped breakers. The pre-charge PTC thermistor can stop the circuit until the correct voltage is applied and reset itself. PTC Thermistor Protection for a Pre-Charge Circuit for Lithium-Ion Batteries Web二、mosfet和igbt的功率区别. igbt可以提供很大的功率、电流和电压，但是频率并不太高。目前的igbt硬开关速度可以达到100khz，已经不错了。但是，相对于mosfet的工作频率来说还是杯水车薪，mosfet可以工作到几百khz、mhz，甚至几十mhz的射频产品。
