BCIM

The BCIM is a prototype IGBT gate driver board. This board features a MC3PHACVPE three phase AC motor controller IC at its core. The BCIM board is designed to provide an interface between the controller and IPM design kits. It provides PWM signals for the IGBTs in the three legs of a 3 phase inverter plus a brake signal. Using this board along with 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 BCIM will use a maximum of 200mA from the 5V DC 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 to 5V) and 19V (24V to 5V) which will mean an additional 0.6W to 3.8W of power loss. The 24V or 15V control power that is needed for the IPM development boards can be shared with the BCIM board or separate power supplies can be used.

• It has three connectors, CN1, CN2 and CN3
• The BCIM can also be connected to the super mini DIP IPM and mini DIP IPM demonstration boards
• Two feedback controls, the fault signal feedback and the bus voltage level feedback
