Abstract:
In one embodiment, a method receives a shed comparison signal that is based on a comparison of a voltage detected from a voltage converter to a reference voltage and receives a zero cross signal that indicates whether a current from the voltage converter has crossed zero. The shed comparison signal is sampled for a first number of clock cycles to generate shed comparison sampled values. Also, the zero cross signal is sampled for a second number of clock cycles to generate zero cross sampled values where the second number of clock cycles are less than the first number of clock cycles. The method determines a change between a shed state and an unshed state based on the shed comparison sampled values for the first number of clock cycles or the zero cross sampled values for the second number of clock cycles.
