Abstract

A resonant converter includes an inverter for generating an AC voltage which is fed to a resonant arrangement with a capacitor and a transformer. The circuit provides two types of secondary units, each having a secondary winding of the transformer and at least one rectifier element. Secondary units of the first and second type are then distinguished by opposite orientation. At least two output voltages are delivered on the output, a first output voltage of which being supplied as a direct output of a first-type secondary unit and a second output voltage as a “stack output” of a first-type secondary unit and a second-type secondary unit. The two output voltages can be regulated separately and independently of each other with a regulating device by suitably choosing frequency and duty cycle of a pulse width modulated voltage generated by the inverter driven by the regulating device.
