EPC has introduced an evaluation board implementing a 40Arms (60A peak) three-phase inverter that will run from 30V to 130V. 10 hp motor
Called EPC91200, it is “suitable for 80 and 110V battery systems commonly used in industrial automation, agricultural machinery and material handling equipment like forklifts,” according to the company.
The inverter is designed around EPC’s 150V 3mΩ EPC2305 GaN HEMT, a devie developed for 96V battery use.
PWM switching is across across 20 to 150kHz (100kHz nominal) and the board includes gate drivers, regulated auxiliary power rails for housekeeping, sensors for voltage, current and temperature, a shaft encoder interface and protection features.
What it does not include, is any form of signal generator or control loop.
It “works with multiple controller boards from manufacturers like STMicroelectronics, Texas Instruments and Microchip”, said EPC.
Filed oriented control is expected.
Physically the EPC91200 board measures 130 x 100mm, and it is available from Digi-Key.
