600V – 30A IPM Module Carrier Board for Variable Frequency Drive (VFD)


This compact IPM module circuit provides a fully-featured, high-performance inverter output stage for AC Induction, BLDC, and PMSM motors. The circuit is based on FNA23060 chip which integrates the optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features: under-voltage lockouts, over-current shutdown, temperature sensing, and fault reporting. The built-in, high-speed HVIC requires only a single supply of 15V and translates the incoming logic-level gate inputs to high-voltage, high-current drive signals to properly drive the module’s internal IGBTs. On-Board optional current sense circuit can be used to monitor the current. LM317 regulator provides 5V DC output to drive op-amp current sense circuit. LED D4 and D5 indicate 5V power and 15V power. Board has an option for 3 current sense resistors. An external 3 phase current circuit is required for 3 phase current sense circuit, if a single current sense circuit is required, solder all 3 phase NU+, NV+, NW+ together and use U4 op-amp circuit, in this case, solder R16. The current sense circuit is built using op-amp based, the gain of the circuit can be set as per user requirement. The board works with lethal high voltage DC and requires extra care while testing.  PFC-based DC power supply is recommended to power the board.
