| Abstract: | In this paper, a circuit which consists of two capacitors and a conductor is proposed to achieve the function of step-down transformer. Theoretical analysis is made and test result under the condition of power frequency for this circuit is also given. The potential application of the circuit is discussed. The circuit has a number of advantages. When the transformer is replaced with the circuit in power supply system, it can feed leading wattless power, is without short circuit problem and has high efficiency. Its V-A output characteristic has the shape of falling elliptical curve, which is similar to AC welding transformer. |
