<p>An object of the invention is to provide a voltage booster capable of boosting an output voltage of a DC voltage source. Two pairs of one reactor and one DC power source are connected in series to each other. Each pair is short circuited by each parallel switch. A power loss of the PWM-switched parallel switch is decreased. A series switch for connecting two pairs can be provided. In another case, a voltage booster for applying a boost voltage to a power converter driving a switched reluctance motor consists of an output switch and a smoothing capacitor in order to accumulate a residual magnetic energy of the switched reluctance motor. The rising-up and the falling-down of phase currents of the switched reluctance motor becomes quickly.</p> |
