Abstract: A power supply as discussed herein includes a controller. The controller receives an output voltage feedback signal outputted from a resonant power converter. The output voltage feedback signal tracks a magnitude of an output voltage outputted from the resonant power converter to power a load. An error voltage generator generates an error voltage signal based on a comparison of the output voltage feedback signal to a setpoint reference voltage. The output voltage feedback signal derives a control period setting from an error voltage. The controller controls switching of switches in the resonant power converter in accordance with the derived control period setting.
