Patent ID: 8773077

Claim:
A controller block for a battery charger including a power converter, comprising: a plurality of parametric sensors for providing a plurality of sensed parameters provided by said power converter while said power converter is connected between a power source and at least one battery for charging said battery, said sensed parameters including a sensed Vin signal, a sensed Vout signal and a sensed Iout signal; a battery current regulator (BCR) coupled to receive said sensed Iout signal and an Iout reference, said BCR outputting a first duty cycle control signal; an input voltage regulator (IVR) for receiving said sensed Vin signal and a Vin reference, said IVR providing a second duty cycle control signal; a processor coupled to receive said sensed Iout signal, said processor utilizing a Maximum Power Point Tracking (MPPT) algorithm for providing said Vin reference to said IVR, and a selection block coupled to receive said first and said second duty cycle control signals, said selection block forwarding one of said first and said second duty cycle control signals as a duty cycle control signal to said power converter.
