Where a Common-Mode Choke Moves the Carrier Resonance: Cpv-Resolved Sizing for Two-Stage H5 Inverters

Transformerless H5 inverters serve the 5 kW residential photovoltaic (PV) segment, but their common-mode (CM) leakage current follows the rain and humidity-driven parasitic capacitance Cpv — which, to our knowledge, no prior work connects to a resonance-safe choke size. We propos...
