The inventive technology, in certain embodiments, may be generally described as a solar power generation system with a converter, which may potentially include two or more sub-converters, established intermediately of one or more strings of solar panels. Particular embodiments may involve sweet spot operation in order to achieve improvements in efficiency, and bucking of open circuit voltages by the converter in order that more panels may be placed on an individual string or substring, reducing the number of strings required for a given design, and achieving overall system and array manufacture savings.

A multi-level voltage regulator system/method providing discrete regulation of a DC-DC intermediate bus converter (IBC) output voltage (Vout) is disclosed. The disclosed system/method allows IBC Vout to be regulated in discrete steps during periods where IBC input voltage (Vin) falls below nominal operating values. Rather than shutting down or degrading IBC Vout in an unpredictable non-linear fashion based on IBC input/loading, IBC Vout is regulated in fixed discrete steps, allowing IBC-connected point-of-load (POL) converters to obtain stable power input that is well-defined over IBC Vin. IBC operating parameters may define multi-dimensional operational state spaces of IBC Vout regulation that ensure optimum power flow to attached POLs while maintaining operational stability within the IBC regulator. Instabilities in IBC/POL performance across variations in IBC Vin, load transients, POL loading, and environmental variables may be prevented using Vin voltage step hysteresis.
