On Semi公司的NFAM5065L4B是全集成逆变器功率模块,包括一个单独高边栅极驱动器,六个IGBT和温度传感器(VTS),适合驱动永磁同步马达(PMSM),无刷直流电动机(BLDC)和AC异步马达.IGBT可配置成有单独发射极连接三相桥,用于具有控制算法选择最大灵活性的低边腿.NFAM5065L4B具有单独驱动的三相650V 50A IGBT模块,有源逻辑接口,集成的自举二极管和电阻,内置了欠压保护(UVP),单独的低边IGBT发射器连接,以便对每相电流进行检测,满足UL1557 资质(文件No.339285).器件是无铅和RoHS兼容.主要用在工业驱动,工业泵,工业风扇和工业自动化.本文介绍了NFAM5065L4B主要特性,等效框图,应用电路以及4KW三相马达驱动参考设计SECO-4KW-65SPM31-GEVB主要特性,电路图和材料清单.

The NFAM5065L4B is a fully-integrated inverter power moduleconsisting of an independent High side gate driver, LVIC, six IGBTsand a temperature sensor (VTS), suitable for driving permanentmagnet synchronous (PMSM) motors, brushless DC (BLDC) motorsand AC asynchronous motors. The IGBTs are configured ina three-phase bridge with separate emitter connections for the lowerlegs for maximum flexibility in the choice of control algorithm.The power stage has under voltage lockout protection (UVP).

Internal boost diodes are provided for high side gate boost drive.

NFAM5065L4B主要特性:

• Three-phase 650 V, 50 A IGBT Module with Independent Drivers

• Active Logic Interface

• Built-in Undervoltage Protection (UVP)
