Overview

This reference design realizes a three-phase inverter subsystem for AC inverter drives and servo drives using an intelligent power module (IPM). Reinforced isolation is present between the microcontroller (MCU) and the IPM-based power stage. The PWM signals are isolated using the single-package, six-channel digital isolator, ISO7760. In-phase current sensing is done in two motor phases using the isolated delta-sigma modulator, AMC1303M0520. DC bus voltage feedback and module temperature feedback is provided to the MCU through isolated delta-sigma modulators, AMC1303M2520. This reference design is controlled by a C2000™ MCU.

Features

Power stage suited for 200-V to 480-V AC drives with continuous current rating up to 5 Arms and peak current rating of 10 Apk using a 1200-V, 15-A IPM
Reinforced isolation between controller and power stage
Single-package reinforced isolator ISO7760 for six PWM signals reduces BOM count and PCB footprint when compared to multiple optoisolators
Excellent propagation delay matching of isolator channels allows for smaller dead time, resulting in reduced inverter output distortions and better efficiency
PWM isolator with very low current consumption and self heating allows powering from 15-V IPM supply with small footprint LDO
IEC61800-3 EMC immunity for EFT up to 4 kV on motor power cable
