Series resonant converter with a regulation circuit

摘要

Series resonance converter includes a control circuit (8) for controlling the converters output voltage, and the control circuit is used for processing a first actual value (Uout) which depends on the converter output voltage (uout(t)) and for processing a second output value (Uc) which depends on the current flowing through the series resonance circuit elements (C,L,R) of the converter (1). The control circuit (8) is used for supplying a manipulated variable (u) which determines the pulse duty factor of a pulse-width modulated voltage (upwm (t)) supplied to the series resonance circuit of the converter.
