EV18H47A

EV18H47A is a MCS MCLV-48V-300W development `board. The Motor Control System (MCS) development tool Ecosystem enables rapid prototyping of motor control designs using the dsPIC® DSCs, SAM, PIC32MK, PIC32MC and PIC32C MCUs. The MCS development tools consist of modular and interchangeable inverter boards, controller boards (DIMs) and expansion boards. The MCLV-48V-300W inverter board is targeted to drive a low-voltage (12-48V) 3-phase PMSM or BLDC motor up to 25A RMS continuous per phase at 25°C. It features user interface elements such as two debug LEDs, 2 push buttons, 1 potentiometer, MCU reset push button, fault reset push button, power-on status indication LED, 6 PWM indication LEDs, 2 dual row headers for interfacing Microchip Xplained Pro add-on boards or other user interface boards to extend the application functionality, On-board EEPROM for storing board or motor configuration information.

• Motor phase current feedback to implement Field Oriented Control (FOC) of a PMSM/BLDC motor
• DC bus current feedback for OCP and to demonstrate a single shunt current reconstruction algorithm
• DC bus voltage feedback for overvoltage protection and DC bus compensation
• Phase voltage feedback to implement sensorless Back-EMF (BEMF) control or flying start (windmilling)
• Optional analogue sensor (e.g., thermistor) interface circuit
• Hall sensor interface, MOSFET temperature measurement, QEI for an optical/incremental shaft encoder
• Overvoltage and current protection circuits
• PICkit™ on-board 4 (PKOB4) for programming and debugging
• Optional ICSP™ header for interfacing a Microchip programmer/debugger
• Dynamic brake circuit to support regenerative braking applications
