Abstract
A resonant converter has a resonant capacitor between the input stage and the output stage. An output inductor arrangement of the output stage has a first inductor component and a second inductor component. A first output is coupled to a reference output by both of the first and second inductor components in series and connects to a first load with a first (high) forward voltage. A second output is coupled to the reference output by only one of the first and second inductor components, and connects to a second load with a second (low) forward voltage. Only one output connects to a corresponding load at one time. This enables a large output voltage range with low total harmonic distortion and/or low voltage stress on the components of the input and output stages.
