Overview

The Microchip dsPICDEM™ MCHV-2 Development Board aids in the rapid evaluation and development of a wide variety of high-voltage motor control applications. This development board is targeted to control Brushless DC (BLDC) motors, Permanent Magnet Synchronous Motors (PMSM), and AC Induction Motors (ACIM) in both sensored or sensorless operation. The MCHV-2 can be configured to use with Microchip’s motor control dsPIC Digital Signal Controllers (DSCs), supporting 100-pin Plug-in Modules (PIMs) for the dsPIC33F, E and C motor control devices. There is also an option to mount a 28-pin SOIC dsPIC33 DSC device directly. The development board uses a three-phase Integrated Power Module device (IPM) that contains the motor inverter and the gate driver’s circuitry. The circuit drives 3-phase motors using different control techniques without requiring any additional hardware. The MCHV-2 supports using either the internal op amps found on dsPIC33E and dsPIC33C motor control DSCs, or the external op amps found on the MCHV-2 board for current sensing.

The rated continuous output current from the inverter is 6.5A (RMS). This allows up to approximately 2 kVA output when running from a 208V to 230V single-phase input voltage in a maximum 30ºC (85ºF) ambient temperature environment. Therefore, the development board is ideally suited for running a standard 3-phase AC Induction Motor of up to 1.4 kW (1.8 HP) rating or a slightly higher rated industrial servo-motor. The IPM is capable of driving other types of motors and electrical loads that do not exceed the maximum power limit and are predominantly inductive. Furthermore, single-phase loads can be driven using one or two of the inverter outputs. The unit is capable of operating from 85VAC up to a maximum of 265VAC.

The MCHV-2 (DM330023-2) replaces and is fully backwards compatible with the previous MCHV (DM330023) and all motor control PIMs.
