The Parallel Loaded Resonant Converter for the Application of DC to DC Energy Conversions?

The resonant power conversion having many advantages over conventionally adopted pulse width modulation that includes a high efficiency, low electromagnetic interference, small volume, low switching losses, and light weight of components due to a high switching frequency, and low reverse recovery losses in diodes owing to a low di/dt at switching instant. This paper presents the doubly loaded resonant power converter for dc to dc conversion. The proposed circuit consists of half bridge inverter, Double LCL filter and diode bridge rectifier. The output is filtered by a low pass filter. A MATLAB based simulation circuit is designed and verified for the different loads. The proposed novel loaded resonant circuit reaches up to 92% efficiency. The circuit result performs a satisfactory performance of the topology. The loaded resonant power conversion circuit is used in telecom power supplies, solar energy generation systems, UPS, battery charging system, switching circuits and power electronic circuits.
