Analog Devices Inc. EV-MCS-ISOINVEP-Z電源板

Analog Devices EV-MCS-ISOINVEP-Z is offered as the power board for the Isolated Inverter Enhanced Protection Platform. With the EV-MCS-ISOINVEP-Z Power Board, designers can evaluate Analog Devices’ isolated sigma-delta converters for voltage and current measurement, isolated gate drivers, and power controllers in a full system application at DC bus levels up to 800V.

The EV-MCS-ISOINVEP-Z Power Board is designed to operate from a DC input supply in the 24V_DC-800V_DC range. EV-MCS-ISOINVEP-Z provides a 3-phase variable frequency, variable voltage, and variable deadtime PWM output to a motor or load. The inverter used with the EV-MCS-ISOINVEP-Z comes in an open-loop platform without any feedback loops. The inverter consists of a 3-phase six-IGBT bridge, 1200V IGBTs, and six ADuM4135 isolated gate drivers with desaturation protection and Miller clamp. AD7403 Sigma-Delta Modulators deliver isolated current and voltage feedback to the control-side of the board. The isolated sigma-delta current and voltage feedback support the development of sensorless control algorithms. The feedback signals allow the designer to close the control loop.

The EV-MCS-ISOINVEP-Z Power Board serves as a highly configurable, system-oriented platform for Analog Devices’ isolation technology with multiple test-point and connectivity options. An easy-plug connector allows a controller connection to an ADSP-CM408 processor evaluation board. Using the EV-MCS-ISOINVEP-Z Power Board with the ADSP-CM408 EZ Kit and demo software enables motor start-stop, open loop volts/hertz speed control, and data visualization. The 0.1” headers provide alternative connectivity to other processor or FPGA platforms.
