Abstract
A DC voltage divider for converting electric energy which includes capacitors, diodes and switches. The divider is a device for unidirectional transmission, on the condition that its input and output operate alternatively. The divider divides a high voltage input into a low voltage DC output. The transmission ratio of input impedance to output impedance is equal to N.sup.2, where N is the number of capacitors included in the divider. The divider can be used in electric power supply devices to replace transformers to transform an input voltage to a lower value. The divider also has high power output and efficiency. The divider is small in size, low in cost, and its output can be controlled by adjusting the operating frequency.
