INTRODUCTION
The dsPICDEM MC1L 3-Phase Low Voltage Power Module is intended to aid the user
in the rapid evaluation and development of a wide variety of low voltage DC motor
control applications using the dsPIC
includes several Microchip analog components, as well as a PIC
used to provide isolated voltage feedback. The main components of the system are
shown in Figure 1-1.
The unit is capable of operating from any voltage up to a maximum of 48V (average)
and 58V (peak). It is therefore suitable for use on a very wide range of applications.
These include conventional commercial and industrial applications running off up to
48V DC supplies, as well as automotive applications including the new 42V bus
standard. Protection is provided for accidental reverse connection of the DC input, as
well as for motor and wiring short circuits.
The continuous rated input current is 15A (RMS). The continuous rated output current
from the inverter is also 15A (RMS). This results in the maximum output power being
linearly related to the input voltage. Approximately 400VA/300W output may be
achieved when running from a 24 DC input voltage up to a 30°C (85F) ambient. Thus,
the system is ideally suited to running quite large 3-phase brushless DC motors or
specialist induction machines wound for operation at low voltage. 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 user should read Section 1.2 “Using The Motor Control 3-Phase Low Power
Module” and Section 1.4 “Current and Power Limitations” carefully before using
the system.
