摘要:
Methods, apparatuses and systems provide technology for a high frequency alternating-current (HFAC) distribution network for a vehicle that includes a plurality of HFAC zones coupled to a direct-current (DC) power source, the plurality of HFAC zones disbursed within the vehicle, where each HFAC zone includes a HFAC resonant inverter to convert DC power to HFAC power and a HFAC bus coupled to the HFAC resonant inverter, the HFAC bus to distribute the HFAC power to one or more loads. The technology includes a CLCL resonant tank circuit having two capacitors and two inductors, a push-pull circuit coupled to the CLCL resonant tank circuit, the push-pull circuit including a pair of switches, and a transformer to couple the inverter to the HFAC bus.
