EPC9146KITA – 400 W Motor Drive Evaluation Kit

EPC9146 Development Kit

The EPC9146 power board contains three independently controlled half bridge circuits, featuring the EPC2152 monolithic ePower™ Stage with integrated gate driver, 80 V maximum device voltage, 15 A maximum output current. The board can also be configured for multi-phase DC to DC conversion and the EPC2152 supports PWM switching frequencies up to 3 MHz. The EPC9146 contains critical functions for power drive application, including monolithic power stage with integrated gate driver, regulated auxiliary power rails for housekeeping supplies, voltage, and temperature sense, accurate current sense, protection functions and so on. Paired together with EPC9147A, it allows the user to control this power board directly through the Microchip dsPIC33EP256MC506 microcontroller board leveraging existing resources for quick development purposes.
