PROBLEM TO BE SOLVED: To provide a DC voltage unit by converting a pulse width modulation signal (PWM). SOLUTION: The DC voltage unit by the conversion of the pulse width modulation signal (PWM), at least with a switch part can generate function of conduction (on) and non-conduction (off), comprises a driving part connected to the switch; generates on and off functions in the switch, comprises a first constant voltage connected to the switch; generates the voltage, comprises a bridge-connecting part connected to the first constant voltage; maintains unidirectional transmission in the first constant voltage, comprising a second constant voltage connected to the bridge connector, generates the voltage, comprising a condensed member connected to the second constant-voltage part, can charge and discharge the electrical power of which the first constant-voltage part and the second constant-voltage part transmit; and adjusts the output power, by controlling a duty cycle of the inputted PWM signal.
