1000 W dual stage DC-AC converter demonstration board based on the STP160N75F3

This application note provides design guidelines and performance characterization of the STEVAL-ISV001V1 demonstration board.

This board implements a 1 kW dual stage DC-AC converter, suitable for use in batterypowered uninterruptible power supplies (UPS) or photovoltaic (PV) standalone systems.

The converter is fed by a low DC input voltage varying from 20 V to 28 V, and is capable of supplying up to 1 kW of output power on a single-phase AC load. These features are possible thanks to a dual stage conversion topology that includes an efficient step-up pushpull DC-DC converter, which produces a regulated high-voltage DC bus and a sinusoidal HBridge PWM inverter to generate a 50 Hz, 230 Vrms output sine wave. Other key features of the system proposed are high power density, high switching frequency and efficiency greater than 90% over a wide output load range
