This thesis outlines the research, design and implementation of a high power direct current (DC) to alternating current (AC) inverter with particular focus on remote applications. The final design consisted of a two-stage converter consisting of a DC-DC Step Up stage and a DC-AC Inverter stage. The DC-DC Step up converter was based on a Push-Pull design and steps 24Vdc to 400Vdc. The inverter stage was based on a full-bridge configuration that generates a 240Vac output from 400Vdc. The Microprocessor was a Hitachi SH1 used both current and voltage mode control to implement a PI adaptive control system. The system that was tested and implemented could generate 240Vac at 100W but developed the potential to operate at considerably higher power with far more advanced control algorithms.
