DM330023-3

DM330023-3 is a dsPICDEM™ MCHV-3 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-3 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.

• Maximum output 1000W at 400V
• Input voltage range from 85VAC to 265VAC
• Current feedback circuitry and zero-crossing detection
• VAC input voltage sensing
• DC bus sensing and over-current protection
• Current sensing using external op-amps on the MCHV-3 board or internal op amps on certain dsPIC DSCs
• Built-in power supplies
• Built-in isolated debugger / programmer
• Real time debug with DMCI integrated MPLAB® or X2C Scope 
• Motor control interfaces
