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.

Note: It is advisable to read the datasheet of FNA23060 to configure and control this board, current trip, Fault output, input PWM sequence, Over temperature output.
The board operates at lethal voltages and has bulk capacitors that store significant charge. Accidental contact can lead to lab equipment damage, personnel injury, and may be fatal. Please be exceptionally careful when probing and handling this board. Always observe normal laboratory precautions.

Current Sense: the board has provision to mount 3 shunt resistors if 3 phase current monitor is required, in this case, use R16, R17, R19 resistors. This will require 3 phase current to voltage op-amp circuit, the board has provision to measure a single current sense, in this case, solder all 3 emitters of IGBTs (Pin 5,6,7) and use U4 op-amp circuit to monitor the current of the motor.

Over Current:  The IPM module has an inbuilt separate over-current shutdown circuit, over-current is set using R23, R24, and C27, refer to datasheet of IC to calculate the Over Current shutdown threshold as per requirement.

Signal Input Pins: Pins IN(UL), IN(VL), IN(WL), IN(UH), IN(VH), IN(WH), These pins control the operation of the built−in IGBTs. They are activated by voltage input signals. The terminals are internally connected to a Schmitt−trigger circuit composed of 5 V−class CMOS. The signal logic of these pins is active HIGH. The IGBT associated with each of these pins is turned ON when a sufficient logic voltage is applied to these pins. The wiring of each input should be as short as possible to protect the Motion against noise influences. To prevent signal oscillations, RC (Resistors and capacitors) R1, R5, R6, R11, R12, R13, C3, C4, C5, C11, C12, C13) provided at all 6 inputs signals.

Power Supply: 15V DC supply required to drive the Logic gate driver circuit Use Pin 1and 2 of connector CN1 to apply logic supply. U2 LM317 regulator provides 5V DC to op-amp circuit for current sense.  CN2 screw terminals are provided to power the load.

Power LED: D4 5V LED, D5 15V LED

Motor Supply Voltage Feedback: CN5 Connector provides Bus voltage (Motor Supply) feedback (Output 3.2V when 390V, 0.75V when Bus V=90V)

Motor Connections: 4 Pin screw terminal CN3 for motor connections, pin 1 motor phase W, pin 2 motor phase V, pin 3 motor phase U

Heatsink: Large size heatsink and fan is very important to cool down the IPM module.

I’m doing research on making a 3 phase controller using IPM ikcm15l60gd, I’m having trouble getting a max voltage of 48 on phase
do you have any suggestions for this problem, thank you for your attention
