By adopting the concept of virtual quadrature source (VQS), a novel method for power transmission control—ac–ac converter with controllable phase and amplitude (ACCPA) was proposed, which has two control variables and is able to continuously regulate the phase and the amplitude of its output voltage independently. The operation principle was studied in detail, and the relationship with the optimization...
The concept of virtual quadrature source (VQS) was introduced and a novel phase and amplitude controllable voltage regulator (PACVR) was proposed. The single-phase PACVR comprises of a Buck type AC chopper, a 3rd harmonic trap and a Boost type AC chopper. In relation to the input voltage, the phase and amplitude of the output voltage are regulated respectively. The Buck type AC chopper and the 3rd...
