dsPICDEM MC1H 3-PHASE
HIGH VOLTAGE POWER MODULE
Chapter 1. Set Up and Operation
1.1
INTRODUCTION
The Microchip dsPICDEM MC1H 3-Phase High Voltage Power Module is intended to
aid the user in the rapid evaluation and development of a wide variety of motor control
applications using the dsPIC
microcontroller. The design of the system includes
Microchip analog components, as well as a PIC
microcontroller used to provide
isolated voltage feedback. The main components of the system are shown in
Figure 1-2.
The rated continuous output current from the inverter is 2.5A (RMS). This allows up to
approximately 0.8 kVA output when running from a 208V to 230V single-phase input
voltage in a maximum 30°C (85F) ambient temperature environment. Thus, the system
is ideally suited to running a standard 3-Phase Induction Motor of up to 0.55 kW
(0.75 HP) rating or an industrial servomotor of slightly higher rating. 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 1 or 2 of the inverter outputs.
The unit is capable of operating from any AC voltage up to a maximum of 265V.
Operation at voltages beneath 208V requires that the output power is reduced owing
to inverter output and AC input stage current limits. A more detailed explanation of
power limitations is given in
Section 1.4 “Detailed Description of Operation”
.
The user should read
Section 1.3 “Current and Power Limitations”
and
Section
1.4 “Detailed Description of Operation”
carefully before using the system.
