STEVAL-ISV001V1
1000 W dual stage DC-AC converter demonstration board
based on the STP160N75F3
Features
■ Nominal input voltage: 24 V
■ Output voltage: 230 Vrms, 50 Hz
■ Output power: 1 kW
■ Efficiency: 90%
■ Switching frequency: 100 kHz (DC-DC); 16
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.
