10 Amp 400V DC Intelligent power module board has been designed using ON Semiconductors STK544UC62K. This Inverter IPM module includes the output stage of a 3-phase inverter, pre-drive circuits, bootstrap circuits, protection circuits, op-amp based current sense circuit, comparator circuit for fault/Over current output, Bus voltage output, onboard 5V DC regulator for op-amp circuit. This board can be used to drive AC Induction, BLDC, PMSM motors and Brushed DC Motors. The module integrates optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features including under-voltage or over voltage , over-current , 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 various power applications and also can be used as H-Bridge for brushed DC motor. The module mainly helps to drive Hall sensor based, encoder based motors and 3 Phase AC Motors. The IC has Built-in dead-time for shoot-thru protection. Internal substrate temperature is measured with an internal pulled up thermistor. PWM frequency is up to 20 KHz. The board can be used in application like small machines as speed controller, washing machine, refrigerator, Air condition, automation, AC motor speed controller, dc motor speed controller, brushless dc motor driver, ac servo driver.
