Summary of INTELIGENT POWER MODULE (IPM) BOARD FOR BRUSHLESS MOTORS
This article describes an Intelligent Power Module (IPM) board utilizing the Fairchild FSBS5CH60 IC to drive AC Induction, BLDC, BLAC, and PMSM motors. The module integrates optimized gate drives for IGBTs, offering protection features like under-voltage lockout and over-current shutdown. It connects to a microcontroller via shunt resistors for current feedback and can function as an H-Bridge for brushed DC motors. However, it currently supports Hall sensor or encoder-based control but does not support Field-Oriented Control (FOC) algorithms.
Parts used in the IPM Board for Brushless Motors:
- Fairchild FSBS5CH60 IC
- Motion SPM (Smart Power Module)
- Bulk capacitors
- Microcontroller (MCU) interface circuitry
- Shunt resistor
- High-speed HVIC
Intelligent Power Module (IPM) board has been designed using FSBS5CH60 IC from Fairchild, which provides a fully-featured, high-performance inverter output stage for AC Induction, BLDC, and PMSM motors. These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features including under-voltage lockouts, over-current shutdown, and fault reporting. The built-in, high-speed HVIC requires only a single supply voltage and translates the incoming logic-level gate inputs to the high-voltage, high-current drive signals required to properly drive the module’s internal IGBTs. Separate negative IGBT terminals are connected to shunt resistor to provide the current feedback to the micro-controller. This IPM module helps to develop lots of power applications and also can be used as H-Bridge for brushed DC motor. The module is manly helps to drive Hall sensor based or encoder based motors, it doesn’t support FOC algorithm, FOC based IPM board is under development and will be publish soon.
This board designed to evaluate Fairchild Semiconductor’s FSBS5CH60. The motion SPM is installed as the motor power module on the board to drive a three-phase AC Induction Motor (ACIM), Brushless DC (BLDC) motor, Brushless AC (BLAC) motor, or Permanent-Magnet Synchronous Motor (PMSM). The board has bulk capacitors and microcontroller (MCU) interface circuitry. As this board is designed for a wide variety of motor types, not all included circuitry is required for all types of motors. Some motor types may require some additional circuitry be added, depending on the control algorithms being implemented.
