In a switching power supply device, the operating voltage is supplied to the power-factor improvement control circuit when the switching power supply device is operating under normal operating load. Thereby, the booster chopper circuit is controlled by the power-factor improvement control circuit so as to improve the power factor of the device. By contrast, during the non-oscillation period while the switching control circuit is in the intermittent oscillation mode when the power consumption is small, the voltage induced in the auxiliary winding drops. Accordingly, the voltage of the auxiliary power supply also drops. Furthermore, when the driving voltage to be supplied to the power-factor improvement control circuit is reduced below the operating voltage thereof by the voltage reduction circuit, the power-factor improvement control circuit stops functioning, thereby reducing power consumption accordingly.

In a hybrid vehicle, once an engine is started in response to prohibition of an operation stop of the engine based on a deterioration factor, the operation stop of the engine is not allowed irrespective of the value of the deterioration factor D until elapse of a certain time period since the start of the engine. The deterioration factor has an increase according to discharge of a battery and a decrease according to charge of the battery and represents start of deterioration of the battery when exceeding a specific reference value. Such prohibition of the engine operation stop prevents a stop of the engine within a relatively short time period after a start of the engine based on the deterioration factor. This arrangement effectively prevents the driver from feeling odd and uncomfortable due to frequent stops and starts of the engine based on the deterioration factor, which is not apparently correlated to the driver's accelerating operations.

Based on the transmission timings allocated to the respective ONUs, the OLT switches the modulation scheme of a modulation-scheme variable burst-mode optical transmitter / receiver by control of a modulation scheme controller.
