Abstract
An electric power converter includes a first capacitor being located between an input terminal and an output terminal, and that connects a first terminal being located between the input terminal and a ground, a reactor that connects through electric contact between the first terminal and the output terminal, a switching element that connects through electric contact between the input terminal and the output terminal, and a control unit that executes a first PWM control process controlling a pulse width of the PWM waveform by on and off of the switching device according to the fluctuation of the output voltage, and that executes a second PWM control process widening a pulse width of the PWM and a duty cycle of a PWM than those of the previous cycle when a pulse width becomes a lower limit.
