Partial-Resonant Flyback Converter Analysis and Comparison to the Standard Flyback Converter
Pulse Width Modulation (PWM) is commonly used in power electronics applications thanks to its simplicity and
effectiveness. However, it suffers from high switching losses, frequency limitation, and need for clamping circuits. Resonant
and partial resonant converters are created to find solutions to these problems. Their main aim is to decrease the switching
losses and enable higher frequency operation. A novel Partial-Resonant Flyback converter was presented in 2014 and its
operation and advantages were explained in this referred paper. This paper aims to conduct a detailed loss analysis between
this referred topology and PWMFlyback. Moreover, some practical issues such as semiconductor switch, inductor, output
capacitor, and gating circuit selection were also compared between two topologies. A simulation model was used for this
purpose and the results were presented.
