DM330023-2 is a dsPICDEM MCHV-2 development system intended to aid the user in rapid evaluation and development of a wide variety of applications using a dsPIC digital signal controller. This system is targeted to BLDC motors, PMSM and ACIM in sensor or sensorless operation. This flexible and cost effective tool can be configured in different ways for use with specialized motor control DSCs. It supports the dsPIC33F and dsPIC33E motor control device family and offers a mounting option to connect either a 28 pin SOIC device or a generic 100 pin PIM. The system has a three phase power module device that contains motor inverter and gate driver's circuitry. The circuit drives a BLDC, PMSM or ACIM motor using different control techniques without requiring any additional hardware. The MCHV-2 supports using either the internal opamps found on certain dsPIC33E products or external opamps found on MCHV-2 board for current sensing. It also has PFC circuitry to meet power regulatory requirements.
