Zusammenfassung:This paper deals with the high pressure lamps fed by SEPIC converter implemented with bidirectional switches with the lamp operation frequency of the main supply so as to prevent the occurrence of destructive acoustic resonance and high efficiency, unitary power factor and low cost. It approached the passive elements design in the circuit, the transfer function and the control equation with its control strategy by DSP controller. At the end is shown the system response.
