Patent number: 10938219Abstract: Methods and apparatus may provide for the adaptive operation of a solar power system (3). Solar energy sources (1) and photovoltaic DC-DC power converters (2) may be interconnected in serial, parallel, or combined arrangements.

Publication number: 20200313567Abstract: An apparatus utilizing additive interleaved switchmode (PWM) power conversion stages, having minimal or no output filter, to achieve high bandwidth or even ideally instantaneous power conversion. The additive process may involve voltage stacking of isolated PWM converters, which are interleaved in time, or may involve a single input power supply and inductively combining output currents of PWM power converters interleaved in time, with either additive circuit having minimal or no output filtering. This circuit may overcome limitations for the frequency of feedback control loops once thought to be physical limitations, such as, fundamental switching frequency, output filter delay and the Nyquist criteria.Type: ApplicationFiled: April 13, 2020Publication date: October 1, 2020Inventors: Robert M.
