摘要： The LC combined transformer is a combination of capacitors, inductors and an electrically-isolated mutual inductor, i.e. conventional transformer; which in principle is a unity-coupled mutual capacitor or a cascade connection of an ideal transformer and unity-coupled mutual capacitor(s). To improve the imperfections of widely-used transformers, by employing the simplest passive-circuit design to attain a perfectly-functional match between mutual capacitors and the mutual inductor, this invention achieves optimal features of current or/and voltage transformation, and introduces a new function of waveform conversion from square to quasi-sine. The ideal current transformer herein is suitable for sinusoidal current measurements, the ideal voltage transformer herein suitable for sinusoidal voltage measurements, and they also could be upgraded to ideal transformers for both current and voltage transformations. This transformer can be designed as power transferable as well as waveform convertible, applicable in power systems or power electronics. Herein also states the design approach of integrated inductor and mutual inductor, and the use of push-pull inductor, materials being fully utilized and sizes decreased.

摘要： This invention presents the LC combined transformer, a combination of capacitances, inductances and an electrically-isolated mutual inductor, i.e. conventional transformer. To improve the imperfections of the widely-used transformers, by means of the simplest passive-circuit design of perfectly-functionally mating mutual capacitors with the mutual inductor, the invention achieves optimal characteristics of current or/and voltage conversions, with a new property of waveform conversion from square-wave to quasi-sinusoid. The ideal current transformers herein are suited to sinusoidal current measurements, the ideal voltage transformers suited to sinusoidal voltage measurements, and they all could be upgraded to ideal transformers, capable of current and voltage conversions. They can also be designed as both power transferable and waveform convertible, applicable in power electronics. Herein also states the design approach of integrated inductor and mutual inductor and the usage of push-pull inductor, materials being fully utilized and sizes greatly decreased.
