dsPICDEM MC1H 3-
PHASE HV MODULE
dsPICDEM MC1H 3-Phase High-Voltage
Power Module
The high-voltage module (Figure 5) connects to an
MC1 board to form a high-voltage BLDC motor control
system. The dsPICDEM MC1H 3-Phase High-Voltage
Power module offers high-voltage isolation, as well as
Fault, overcurrent and overvoltage protection. Each
phase is monitored with fast current sensors and a
robust latching network to disable the outputs in case
any Fault condition occurs. This protection is neces-
sary during code development and prevents accidental
destruction of the drive circuitry due to inadvertent
software issues.
The high-voltage module rectifies a single-phase wall
input voltage of 110 VAC to generate a DC bus voltage
of 165 VDC. Alternatively, it can also rectify an input
wall voltage of 220 VAC to get a DC bus voltage of
330 VDC. This DC bus voltage is then converted to
drive a 3-phase motor.
The hardware can be used to drive ACIM and BLDC
motors. For complete details on the features and
capabilities of this module, refer to the “dsPICDEM
MC1H 3-Phase High-Voltage Power Module User’s
Guide”(DS70096).

LV MODULE
dsPICDEM MC1L 3-Phase Low-Voltage
Power Module
The low-voltage module (Figure 6) connects to an MC1
board to form a low-voltage BLDC motor control
system. The dsPICDEM MC1L 3-Phase Low-Voltage
Power module offers voltage isolation, along with Fault,
overcurrent and overvoltage protection. Each phase is
monitored with fast current sensors and a robust latch-
ing network to disable the outputs in case any Fault
condition occurs. This protection is necessary during
code development and prevents accidental destruction
of the drive circuitry due to inadvertent software issues.
DC voltage is supplied externally from a power supply.
This DC bus voltage is then converted to drive a 3-phase
motor.
The hardware can drive 3-phase low-voltage BLDC
motors. For more details on the features and cap-
abilities of this module, refer to the “dsPICDEM
MC1L 3-Phase Low-Voltage Power Module User’s
Guide (DS70097).
