High power, low voltage DC-DC multiresonant converters

Specific applications need high output current DC-DC converters with very low input voltage or large input voltage dynamic. Zero-voltage-switch multiresonant bridges can be used to solve the problem. Optimum values of components and operating frequencies can be determined to get a good efficiency using all parasitic elements in the resonant cells. Models and tests show good agreement and define the limits of feasibility for given specifications.
