Soft Switched Resonant Converters with Unsymmetrical Control
نویسنده
چکیده
Using PSPICE a resonant dc-dc converters operating at constant frequency was simulated. The paper concentrates on the working of a half bridge topology employing ZVS techniques. The operation of converter with LC filter in the output is discussed. The design and fabrication was done on a 5V, 50W converter using MOSFET to validate the performance of the converter. The converter has illustrated low reverse voltage, less current stresses and negligible conductivity losses owing to unsymmetrical duty ratio operation and zero voltage switching. This topology exhibits the merits of both resonant (zero switching loss) converters and switched mode (low conduction loss) circuits.

Conventional energy sources are fast depleting due to poor conservation practises and excessive usage while the world’s energy demands are growing by minute. Additionally, the cost of producing conventional energy is rising also leading to an increase in harmful environmental pollution. Hence, there is a need to look at alternative energy sources such as sun, water and wind. Photovoltaic (PV) i...

There has been an increasing interest in the soft-switching power conversion technologies in order to overcome the limitations of the hard-switching technologies [1]-[7]. Soft-switching (SS) converters had many advantages over hard-switching (HS) converters. For example, SS converters lower switching losses, reduce voltage/current stress, reduce EMI, and allow a greater high switching frequency...
