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。

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 ? Divided negative dc-link terminals for inverter current sensing applications? Single-grounded power supply due to built-in HVIC? Built-in thermistor for over-temperature monitoring? Isolation rating of 2000Vrms/A41560应用：? AC 100V ~ 253V three-phase inverter drive for small power ac motor drives? Home appliances applications like air conditioner and refrigerator图1。FNA41560内部等效电路和输入/输出引脚图图2。FNA41560典型应用电路图参考设计RD-345参考设计RD-345主要特性：FNA41560600V-15A 3-phase IGBT inverter bridge including control ICs for gate driving and protectionEasy PCB layout due to built-in bootstrap diode and independent VS pinDivided negative DC-link terminals for inverter current-sensing applicationsSingle-grounded power supply due to built-in HVICBuilt-in NTC thermistor for over-temperature monitoringIsolation rating of 2000Vrms/min.1N4749ASilicon planar power Zener diodes, DO-41 glass case24V/1.0W rating Zener diodeFor use in stabilizing and clipping circuits with high power ratingStandard Zener voltage tolerance: ±5%图3。空调器方框图图4。FNA41560 3相逆变器参考设计电路图图5。3相逆变器参考设计PCB布局图
