An apparatus includes a switching circuit, a resonant circuit coupled to an output of the switching circuit, a rectification circuit coupled between the resonant circuit and an output of the apparatus, and a controller coupled to the switching circuit. The controller, during a soft start-up operation of the power supply, is configured to switch a plurality of switches with a variable limited maximum duty cycle at a minimum frequency and after the variable limited maximum duty cycle reaches the limited maximum duty cycle at the minimum frequency, simultaneously switch the frequency to a maximum frequency and switch the duty cycle to a minimum duty cycle at the maximum frequency for a same on-time as the limited maximum duty cycle at the minimum frequency.

Power supply having a resonant topology, method of operating a power supply having a resonant topology and apparatus

At least one example embodiment is directed to a method for controlling a rectifier. The method includes applying a first control signal to a first switch of the rectifier to cause a first current to flow through a first inductor of the rectifier, applying a second control signal to a second switch of the rectifier to cause a second current to flow through a second inductor. The second control signal and the first control signal have a phase difference. The method includes detecting that the first current falls to a first minimum value at a first time, detecting that the second current falls to a second minimum value at a second time, determining a first difference between the first time and the second time, and determining whether to adjust the second control signal based on the first difference to bring the phase difference closer to a target phase difference.
