Abstract
A power conversion system always keeps a constant voltage level relative to the ground potential and shows an improved controllability for the noise compensation current. In the noise reduction circuit of the system, a rectified DC voltage is applied to the positive side output line and the negative side output line. The DC voltage is divided by a pair of capacitors connected in series with the intermediary point held to the ground potential. Thus, the positive side output line can always supply a positive voltage that is held to a constant level relative to the ground potential. Similarly, the negative side output line can always supply a negative voltage that is held to a constant level relative to the ground potential. Additionally, as the transistors are controlled for on/off operations by the amplifier, the noise compensation current flows through the noise reduction circuit between the input grounding terminal of the full-wave rectifier and the ground.
