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.
