Multi-input single-resonant tank llc converter

A method of power conversion, comprising:

• coupling an output from a plurality of electric power sources including a first photovoltaic (PV) panel and a second PV panel, with an output of the first PV panel coupled to a first bridge circuit and an output of the second PV panel coupled to a second bridge circuit, wherein the bridge circuits both have output nodes coupled to a single LLC resonant tank including a first inductor (Lr), a capacitor (Cr) configured together with a transformer comprising a secondary winding and a primary winding that has a magnetizing inductance which that provides a second inductor (Lm) in series with the Lr and the Cr, wherein the primary winding is coupled between an output node of the first bridge circuit (node A) and the second bridge circuit (node B), and a rectifier is coupled to the secondary winding that provides a DC output, and
• controlling power from each of the first and second PV panels using a power controller coupled to the output of the first and second PV panels and switches of the first and second bridge circuits implementing pulse width modulation (PWM) phase shift control to independently implement maximum power point tracking (MPPT) for the first PV panel and the second PV panel.
