Differential power processing (DPP) converters are used within circuit architecture of solar power modules to process the mismatched power between solar elements in a power module. The DPP converters use various topologies to process the mismatched power. These topologies can include a housekeeping power supply where the housekeeping power is coupled to the main bus, or, through various other tapping topologies, including to a subset of PV cell substrings.
