OVERVIEW
The Microchip dsPICDEM™ MCHV Development System is intended to aid the user in
the rapid evaluation and development of a wide variety of motor control applications
using a dsPIC
to control Brushless DC (BLDC) motors, Permanent Magnet Synchronous Motors
(PMSM), and AC Induction Motors (ACIM) in sensor or sensorless operation.
This flexible and cost-effective tool can be configured in different ways for use with
Microchip’s specialized Motor Control DSCs. The dsPICDEM™ MCHV Development
System supports the dsPIC33F Motor Control device family, and offers a mounting
option to connect either a 28-pin SOIC device or a generic 100-pin Plug-In Module
(PIM).
The system has a three-phase power module device that contains the motor inverter
and the gate driver’s circuitry. The circuit drives a BLDC, PMSM, or ACIM motor using
different control techniques without requiring any additional hardware. It also has
Power Factor Correction (PFC) circuitry in order to provide a full set of tools used in
motor control applications. Figure 1-1 provides a photograph of the dsPICDEM™
MCHV Development System. A block diagram that shows the main components of the
system is provided in Figure 1-2.
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 volt-
age in a maximum 30ºC (85ºF) ambient temperature environment. Therefore, the sys-
tem is ideally suited for running a standard 3-Phase Induction Motor of up to 1.4 kW
(1.8 HP) rating or a slightly higher rated industrial servo-motor. The power module 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 90V up to a maximum of 265V. A more detailed
explanation of power limitations is provided in Chapter 4. “Hardware”.
Note:
It is recommended to carefully read the hardware section mentioned above
before attempting to use the system.
