Webproposed to be modified in order to make possible the control of the DC-voltage mean value also in presence of a fully resistive behaviour of the DC-load, being this last condition an imperative constraint for the extension of the introduced passive power factor correction technique. Once modified the controlled rectifier circuit, the PF Passivity is a property of engineering systems, most commonly encountered in analog electronics and control systems. Typically, analog designers use passivity to refer to incrementally passive components and systems, which are incapable of power gain. In contrast, control systems engineers will use passivity to refer to thermodynamically passive ones, which consume, but do not produce, energy. As such, without context or a qualifier, the term passive is ambiguous.
