What is IPM (Intelligent Power Module)?
IPM (Intelligent Power Module) is a high-performance module equipped with a dedicated drive circuit for drawing greater performance from an IGBT chip, and provides a custom IC for executing self-protection functions (short circuit, supply undervoltage, and over-temperature).
Why do small compact inverters use an IPM?
For small compact inverters, using an IPM saves space significantly. The IPM is an highly integrated inverter power stage. The gate drivers are integrated inside the module, and only external digital PWM signals are required to control the IPM.
Can an inverter drive an IPM motor?
To drive an Interior Permanent Magnet (IPM) motor, its magnetic pole positions must be detected. Synchronous motors usually use detectors to achieve this. Simply applying a voltage from an inverter does not enable IPM motor operation, as a sudden deceleration command may not be tracked by the motor rotor.
Which type of IPM is used for high-power inverters?
Type 3 IPMs are used typically for high-power inverters. When all the input PWM signals of IPM have a single reference (type 1 IPM), then a six-channel isolator can be used as shown in the left half of Figure 2. The six-channel digital isolator uses only one device when compared to six optoisolator devices as shown in the right half of Figure 2.
What are the benefits of IPM in a PCB inverter?
The IPM also provides diagnostic features like undervoltage protection on the gate drive power supplies, shoot-through detection in the phase half bridges, and overtemperature detection. The inverter PCB BOM count, gate drive subsystem design, and PCB routing complexity can be greatly minimized.
Does an IPM motor save energy?
A 22kW IPM motor saves energy by having 40% lower power loss compared to a 22kW standard motor. The energy saved can be attributed to the reduced power loss. Figure 7.2 shows the total efficiency of standard, high-efficiency, and IPM motors in different capacities when driven by inverters.
