Smart Power Module for 3-Phase Motor – 5A

This is a Smart power module project designed for Small Power AC Motors. The FNB40560 chip is the heart of the project. A compact inverter project is ideal for small power motors such as fans and pumps. H-bridge configuration can also be created for low current high-voltage brushed DC motors. The Inverter project supports loads up to 5A. The DC power supply voltage is up to 400V_DC. The project operates with 6 PWM signals. The parameters for bootstrap circuit elements are dependent on the PWM algorithm. For 5 kHz of switching frequency Bootstrap capacitors C2, C6, and C8 value is 33uF. Resistor R4, R5, R6, R12, R11, R8 and capacitor C9, C10, C11, C15, C16, C17 prevent improper signal due to surge-noise. ATS pin is provided to monitor the temperature of the IPM. A heatsink is needed for the IPM chip during operation or testing.
