EPC EPC91128/EPC91129 Inverter Eval Boards
Efficient Power Conversion (EPC) EPC91128 / EPC91129 Inverter Evaluation Boards are three-phase BLDC motor-drive inverter boards designed with the EPC23108 and EPC23109 ePower™ Stage ICs, which feature 5.2mΩ typical RDS(on) and 100V maximum device voltage. Both the EPC91128 and EPC91129 demonstration boards offer up to 41Apk (29ARMS) pulsed output current. These EPC evaluation boards feature all necessary critical functions circuits to support a complete motor drive inverter, including gate drivers, regulated auxiliary power rails for housekeeping supplies, voltage and temperature sense, accurate current sense, and protection functions. The EPC91128 and EPC91129 boards measure 81mm x 75mm. Typical applications include E-mobility, drones, and robotics.
Features
- Three-phase inverter based on EPC23108 and EPC23109 ePower Stage ICs with wide input DC voltage range of 14V to 80V
