    摘要： An exhaust gas purification apparatus 4 includes a plasma reactor 7 having gas flow passages 28 through which exhaust gas is to pass, and a power source 8 for supplying power to the plasma reactor 7 with a variable application voltage and/or a variable frequency of the application voltage of the power to be supplied. The exhaust gas purification apparatus 4 is adapted to change the application voltage and/or a pulse recurrence frequency of the application voltage, based on a change in amount of PM and/or flow rate of gas passing through the gas flow passages 28. Accordingly, efficient oxidization of PM in the exhaust gas and suppression of consumption of discharged power are achieved.

    摘要： Startup of motor is reliably executed and sonic noise is reduced. A control circuit controls a selector to apply control to output a full-drive waveform at startup and then output a PWM modulation waveform. The full-drive waveform which is an alternating waveform in which positive and negative are inverted at 180° is output. Then, the PWM drive waveform is selected.
