ABSTRACT:
A power supply converting circuit for eliminating abnormal voltage components, such as an electrical noise component and a surge component, from the commercial alternating current without a transformer and for converting the commercial alternating current into a weak direct current and/or an alternating current having a low voltage to apply the weak direct current and/or the alternating current having a low voltage to a load. A filter filters the commercial alternating current and is connected to main power transmission live lines of the commercial alternating current power. A power level adjusting section receives the filtered alternating current in the filter to convert a power level of the received alternating current. A snubber circuit receives the power level converted alternating current in the power level adjusting section and eliminates the abnormal voltage components of the power level-converted alternating current. A converting section receives the alternating current from which the abnormal voltage components have been eliminated in the snubber circuit and converts a direct current and/or an alternating current having a different level.
