[原创]Onsemi NFAM2065L4B全集成4KW逆变器功率模块解决方案

Onsemi公司的NFAM2065L4B是全集成逆变器功率模块,包括有独立的高边栅极驱动器,六个IGBT和一个温度传感器(VTS),适合于驱动永磁同步马达(PMSM),无刷DC(BLDC)马达和AC异步马达.IGBT配置成三相桥式,具有用于下臂的分立发射极连接,以获得选择控制算法的最大限度灵活性.功率级具有内置欠压锁住保护(UVP),在高边栅极增强驱动中提供内部升压二极管.器件是具有单独驱动器的三相650V 20A IGBT模块,有源逻辑接口,满足UL1557认证(文件号No.E339285),器件是无Pb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NFAM2065L4B主要特性, 等效框图,应用电路,以及开发板SECO−MDK−4KW−65SPM31−GEVB主要特性和指标, 框图和相关电路,以及开发板电路图,材料清单和PCB设计图.

The NFAM2065L4B is a fully−integrated inverter power module consisting of an independent High side gate driver, LVIC, six IGBTs and a temperature sensor (VTS), suitable for driving permanent magnet synchronous (PMSM) motors, brushless DC (BLDC) motors and AC asynchronous motors. The IGBTs are configured in a three−phase bridge with separate emitter connections for the lower legs 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.

NFAM2065L4B主要特性:

• Three−phase 650 V, 20 A IGBT Module with Independent Drivers

• Active Logic Interface
