Abstract: A multi-input power DC-DC converter includes a first and second bridge circuit for receiving power from a first and second electric power source. The first bridge circuit includes a first power switches with a first switch output node in between, and a second bridge circuit for receiving power from a second electric power source including second power switches with a second switch output node in between. At least one of the first and second electric power source is a photovoltaic (PV) panel. A single LLC resonant tank coupled to both the first and second output node is configured together with a transformer including a secondary winding and a primary winding that provides a magnetizing inductance which provides a second inductance for the single LLC resonant tank. A rectifier is coupled to the secondary winding.

Abstract: A power inverter combination includes a half-bridge power inverter including first and second semiconductor power switches receiving input power having an intermediate node therebetween providing an inductor current through an inductor. A controller includes input comparison circuitry receiving the inductor current having outputs coupled to first inputs of pulse width modulation (PWM) generation circuitry, and a predictive control block having an output coupled to second inputs of the PWM generation circuitry. The predictive control block is coupled to receive a measure of Vin and an output voltage at a grid connection point. A memory stores a current control algorithm configured for resetting a PWM period for a switching signal applied to control nodes of the first and second power switch whenever the inductor current reaches a predetermined upper limit or a predetermined lower limit.
