This study presents a new ac circuit element – the mutual capacitor, being a dual of the mutual inductor, which is also a new ac transformer. This element is characteristic of the mutual‐capacitance coupling of a multi‐capacitance system. A unity‐coupled mutual capacitor works as an ideal current or voltage transformer, and incidentally acts as waveform separating when inductor employed or waveform converting from square‐wave to quasi‐sine or waveform filtering, between ports. As a transformer, the mutual capacitor is easy to design, easy for heat cooling, more accurate for current or voltage transformation, dissipating less energy as well as saving materials, suitable for high‐power and high‐voltage applications. Experiments to demonstrate performances of unity‐coupled mutual capacitors are also given.
