STEVAL-ISV001V1

1000 W dual stage DC-AC converter demonstration board

based on the STP160N75F3

Features

kHz (DC-AC)

Description

The STEVAL-ISV001V1 demonstration board

implements a 1 kW dual stage DC-AC converter,

suitable for use in battery powered uninterruptible

power supplies (UPS) or photovoltaic (PV) stand

alone systems. The converter is powered from a

low DC input voltage varying from 20 V to 28 V

and is capable of supplying up to 1 kW output

power on a single phase AC load. These features

are met with a dual stage conversion topology

including an efficient step-up push-pull DC-DC

converter, to produce a regulated high voltage DC

bus, and a sinusoidal h-bridge PWM inverter to

generate a 50 Hz, 230 Vrms output sine wave.

Other relevant features of the proposed system

are high power density, high switching frequency,

galvanic isolation and efficiency greater than 90%

over a wide output load range.
