Single-phase inverter with an integrated high-speed relay and PWM voltage regulator
This article presents the results of a single-phase voltage inverter with stabilized output sine wave and fed from a solar panel for individual consumers in tropical conditions design. The power of the inverter is 0-2 kW, input dc voltage power supply 10-14 V, output voltage of 220 V (± 10%) with THD ≤ 10%. The inverter is designed for using in remote areas under conditions of high humidity and hindered maintenance. The inverter can be operated under pulsed mode of unbalanced loads conditions, it produces sinusoidal output voltage without output voltage modulation.
