Resonance transformer power conditioners

Designs for power conditioning systems based on the resonance transformer have been developed for applications requiring compact, lightweight power supplies ranging from average power levels of 10 kW to over 1 MW. The resonance transformer is a patented concept which depends on a set of resonant LC circuits to produce transformer-like voltage or current gain. Because this approach does not require the magnetic core material associated with a conventional transformer, significant savings in both size and weight can be realized, particularly at higher power levels. Technical issues associated with the conventional transformer, such as coupling of the primary and secondary windings at both high voltages and high frequencies and thermal management of heat generated in the transformer core are also avoided. Several designs have been generated and tested, including a 20 kHz, 10 to 15 kW average power system. This power supply will provide a voltage gain of 50 and weighs less than 100 lb
