Abstract
A galvanic isolated DC-DC and DC-AC power conversion system is coupled to a plurality of DC sources which are derived from a combination of a plurality of single-phase and three-phase AC-DC converters. The DC-DC and DC-AC power conversion system in one embodiment is configured to provide mixed type outputs (mixed frequency, e.g. DC with 50 or 60 Hz, with 400 Hz; mixed voltage levels).
Claims23
A galvanic isolated DC-DC or DC-AC power conversion system coupled to a plurality of DC sources which are derived from a combination of a plurality of single-phase and three-phase AC-DC converters.
A galvanic isolated DC-DC or DC-AC power conversion system coupled to a plurality of DC sources which are derived from a combination of three single-phase and three-phase AC-DC converters, wherein the single-phase and three-phase AC-DC converters together comprise a mixed silicon-carbide (SiC) and silicon (Si) device topology.
A galvanic isolated DC-DC or DC-AC power conversion system coupled to a plurality of DC sources which are derived from a combination of a plurality of single-phase and three-phase AC-DC converters, wherein each galvanically isolated DC-DC converter comprises a pulse width modulated MOSFET H-bridge with all silicon-carbide (SiC) power switches or mixed SiC and Si power switches.
