Classification: CPC G  H | IPC G

Claim 7:
8. The system of claim 6, wherein the controller is configured to:
during the first power cycle:
generate a first de-modulated power signal based on a product of the first oscillating power signal from the first power supply and the first modulation signal;
extract a first DC component from the first de-modulated power signal;
interpret the first input voltage above the maximum power point voltage in response to detecting a negative value for the first DC component in the first de-modulated power signal; and
trigger the first adder to apply a negative voltage gain step at the gain control for the first power supply to decrease the first input voltage toward the maximum power point voltage in response to interpreting the first input voltage falling below the maximum power point voltage; and

during the second power cycle, following the first power cycle:
generate a second de-modulated power signal based on a product of the first oscillating power signal from the first power supply and the second modulation signal;
interpret the first input voltage matching the maximum power point voltage in response to detecting absence of a second DC component in the second de-modulated power signal; and
trigger the second adder to apply a null voltage gain step at the second gain control for the second power supply in response to the first input voltage matching the maximum power point voltage.
