1.6kW, bidirectional micro inverter based on GaN reference design

Overview

TopologyPositive to Negative Converter
Input voltage30-60 V
Output 1230 V / 7 A

Description

This reference design implements a four-channel 1.6 kW single-phase bidirectional micro inverter based on GaN. The reference design supports four identical channels with up to 60 V and ±10 A on the DC side. These channels can be connected to photovoltaic (PV) panels or to 48-V Battery Energy Storage Systems (BESS). On the High-Voltage (HV) side, the reference design is connected to a single-phase ACgrid. The reference design has Low-Voltage (LV) and HV sides isolated by means of a bidirectional fixedfrequency CLLLC converter. The control algorithm for the reference design is implemented in C2000™ MCU.

Features

  • High-power density
  • High-switching frequency to enable small passive EMI filter components
  • Any channel can either operate as PV input or 48V battery storage
  • Single chip controller with one C2000 MCU (DC/AC, DC/DC, MPPT)
  • Good common mode isolation with Isolated DC/DC topology
  • Low overall system solution cost

Typical applications

  • Medical instruments
  • Micro inverter
  • Low-noise filament supplies, Distributed supplies, Telecom supplies, Low-noise isolated USB supplies, Isolated power supply for CAN, RS-485, RS-422, RS-232, SPI, I2C, low-power LAN
