Abstract :
Two novel Clamped-Mode Resonant Converters are proposed which operate at a constant frequency while retaining many desired features of conventional series- and parallel-resonant converters. State-plane analysis techniques are employed to identify all possible operating modes of clamped-mode series-resonant converter and define their mode boundaries. The control-to-output characteristics are derived that specifies the regions for natura; and forced commutation The predicted operating modes are verified using a prototype circuit.
