dc.description.abstractFine particulate matter like carbon soot harms the respiratory system. One approach to reducing soot pollution is microwave-assisted soot oxidation. The magnetron, which generates microwave energy requires a high-voltage gain converter. In this thesis, a DC/DC converter is proposed to supply the two voltages required by a magnetron by utilizing dual resonant circuit modules. By combining the switches of the step-up resonant stage with a bridgeless power factor correction (PFC) stage, an AC/DC topology is proposed. The proposed AC/DC topology allows for a high power factor (PF) and reduced input conduction losses. The converter utilizes a parallel CL resonant circuit with voltage doubler output to achieve a high-voltage gain, and an LLC resonant circuit to provide the step-down. The circuit is then verified through PSIM with a peak of 1.8kW. A proof-of-concept hardware test with AC input testing step-up 822V and step-down 1.3V outputs simultaneously with a 0.96PF is performed.
