Using the BCIM Controller with Powerex IPMs
Introduction:
The BCIM board features a three phase AC motor controller IC at its core. The board is
designed to provide an interface between the controller and Powerex IPM design kits. The
BCIM board provides PWM signals for the IGBTs in the three legs of a 3 phase inverter plus a
brake signal.
Using this board along with Powerex IPM design kits allows designers to be able to quickly
verify their Power circuit layout and also gives them an opportunity to see a working control
circuit layout.
The information in this document pertains only to the board and its external connections. For
information specific to the controller please contact Freescale Semiconductor.
Building the BCIM board:
The BCIM kit comes as a bare board along with all of the parts listed in the bill of materials.
The PCB is a two layer board and all of the components are through hole. You will need to refer
to Figure 4 shown at the end of this document which shows the complete component layout in
order to complete the board.
BCIM Connections:
The BCIM controller board has three connectors, CN1, CN2 and CN3. CN2 is a 2-pin connector
that brings in an 8-24V DC power supply and converts it to a regulated 5V supply for the control
logic. CN1 is a 10-pin connector for bringing out the 5V logic power supply and all of the
control signals for the high and low sides of a three phase inverter plus brake. The 10-pin
connector is also used for bringing the fault feedback to the controller. CN3 is connector that
brings in a divided DC bus voltage for feedback into the MC3PHAC MCU.
BCIM Power Requirements:
The BCIM will use a maximum of 200mA from the 5VDC supply for a total of 1W needed at the
output of the 5V regulator. In addition the 5V regulator will have a voltage drop of anywhere
between 3V (8V-5V) and 19V (24V-5V) which will mean an additional 0.6W to 3.8W of power
loss.
