The recent development of a semiconductor device technology realizes small-size, light-weight, high performance power switching devices. But, reactive elements such as an inductor or a capacitor are still physically large and heavy. On the other hand, the improvement of high speed PWM inverter achieves high performance current control, which is applied to the active filter and so on [2] [4]. If a compact and high efficient reactive component is developed, the power converter technology may drastically change the application field.In this paper, the concept of variable active-passive reactance (VAPAR) which consists of an inverter and passive elements is proposed. The VAPAR behaves like a two terminal reactive element and the produced active reactance component works as a passive reactive component, including in transient state.Authors present the principle of VAPAR and two possible control schemes to realize VAPAR. Through simulations and experiments, it is verified that VAPAR shows reactive characteristics not only in steady state but also in transient state, as proposed, and basic characteristics of both control schemes are clarified.
