Abstract	This paper describes a new boost type rectifier. The proposed converter output DC capacitors do not discharge even in a load short circuit condition. When a load short circuit occurs, the capacitors become a floating state immediately. The stored capacitor energy is supplied to the load again as soon as the short circuit has been cleared. This feature satisfies the requirement of a DC power supply for a load with frequent output short circuits. The proposed converter has the characteristics of a simplified structure, a reduced cost, weight and volume compared with conventional power supplies with frequent output short circuits. Experimental results are presented to verify the usefulness of the proposed converter
