Abstract

Buck-boost type SMR (switched mode rectifier) has the constant DC output power characteristics, so the DC output voltage inversely depends on the DC output (load) current. In this paper, the novel voltage control method for the buck-boost type SMR is reported on theoretical, simulated and experimental bases, when the SMR is operated under the discontinuous current mode (DCM) and also the main semiconductor switch of SMR is operated at the fixed frequency with the fixed switching pulse pattern. This novel voltage control method is applicable to the microprocessor control system
