Fairchild FNA41560 RD-345 1500W空调电源解决方案

Fairchild公司的FNA41560 是运动智能的功率模块，包括有600V-15A 3相IGBT逆变器桥，控制IC和保护电路，逆变器的每相电流可单独监视，内置的温度调节器用来超温监视，绝缘指标2000Vrms/min，主要用在AC 100V ~ 253V三相逆变器驱动以及家用电器如空调和电冰箱，本文介绍了FNA41560主要特性，内部等效电路，典型应用电路图以及参考设计RD-345主要特性，空调器方框图，3相逆变器参考设计电路图和PCB布局图。

It is an advanced motion-smart power module (Motion-SPMTM) that Fairchild has newly developed and designed to provide very compact and high performance ac motor drives mainly targeting low-power inverter-driven application like air conditioner and refrigerator. It combines optimized circuit protection and drive matched to low-loss IGBTs. System reliability is further enhanced by the integrated under-voltage lock-out protection, short-circuit protection, and temperature monitoring. The high speed built-in HVIC provides opto-coupler-less single-supply IGBT gate driving capability that further reduce the overall size of the inverter system design. Each phase current of inverter can be monitored separately due to the divided negative dc terminals.

FNA41560主要特性：

• 600V-15A 3-phase IGBT inverter bridge including control ICs for gate driving and protection

• Easy PCB layout due to built-in bootstrap diode and VS output ..
