PowerIntBridgeSwitch系列300W三相逆变器参考设计DER654
PowerInt公司的BridgeSwitch系列集成了两个高压N-沟功率FREDFET和低高边驱动器,其集成的半桥大大地简化高压逆变器的开发和生产.内部集成的600V功率FREDFET提供超软和超快二极管,非常适合于硬开关逆变器驱动,主要用在2/3相高压PM和BLDC马达驱动器,高达300W逆变器输出功率,包括洗碗机和冰箱的家用电器,高效率空调的冷凝器风扇.本文介绍了BridgeSwitch系列产品亮点,系列框图,采用BRD1265C三相逆变器设计DER654电路图以及采用BridgeSwitch系列马达驱动器300W三相逆变器参考设计DER654主要特性和指标,电路图,材料清单和PCB设计图.
The BridgeSwitch™ family of integrated half-bridges dramaticallysimplifies the development and production of high-voltage inverterdriven 2- or 3-phase PM or BLDC motor drives. It incorporates twohigh-voltage N-channel power FREDFETs with low and high-side driversin a single small-outline package. The internal power FREDFETs offerultra-soft and ultrafast diodes ideally suited for hard switched inverterdrives. Both drivers are self-supplied eliminating the need for anexternal auxiliary power supply. BridgeSwitch provides a uniqueinstantaneous phase current output signal simplifying implementation ofsensor-less control schemes. The low-profile, compact footprint surfacemount package offers extended creepage distances and allows heatsinking of both power FREDFETs through the printed circuit board.
