CPC H02M 3/33515 (2013.01) [G01R 19/16528 (2013.01); G01R 19/175 (2013.01); G05F 1/561 (2013.01); G06G 7/18 (2013.01); H03K 5/24 (2013.01); H02M 1/0025 (2021.05)] | 29 Claims |
1. An apparatus comprising:
a power supply controller operative to:
monitor a voltage of a secondary winding magnetically coupled to a primary winding, the secondary winding operative to receive energy from the primary winding;
derive an integrator voltage based on the monitored voltage from the secondary winding;
control an operational state of a first switch coupled to the secondary winding based on the integrator voltage; and
wherein power supply controller is further operative to activate the first switch to an ON-state in response to detecting that a magnitude of the monitored voltage crosses a first threshold value during a window of time in which a magnitude of the integrator voltage is greater than a second threshold value.
