Brake Function
In order to use the integrated brake switch, an external power resistor should be connected between pins BR
and P of terminal block J5. This resistor should be dimensioned for desired braking performance. Carefully
choose the value of this component to ensure the brake IGBT integrated within the power module remains
below its maximum current capability.
2. Power Module Description
The power module integrates all rectifiers, ultra-fast short circuit rated IGBTs, fast recovery commutation diodes
, brake IGBT and other processing components needed for a 3HP Motor Drive or other loads requiring a 3-
phase variable frequency and/or PWM drive. Semiconductor dice are mounted on a thermally effecient substrate
and housed within a convenient, potted module. When connected to the host PCB, the power components
become configured as a 3-phase input bridge rectifier, and IGBT inverter with current sensing shunt resistors.
An NTC thermistor is bonded to the substrate to furnish the host PCB with accurate temperature reading. A
galvanically isolated metal backplate provides excellent thermal coupling to an external heatsink, which is
necessary for full-load operation.
Circuit Layout within the module is carefully designed to minimize inductance in the power path, reduce noise
during inverter operation and to improve inverter efficiency. The IR2133 host board should be soldered to the
power module pins to complete the assembly. For detailed electrical specifications, please refer to the power
module datasheet.
