  "textContent": "A configuration that converts power from high voltage to low voltage by selectively connecting a predetermined storage element group to a low voltage electrical load from a high voltage power supply formed by connecting storage elements in series. In this configuration, the number of storage elements is set such that the voltage of each storage element group is slightly higher than the rated operating voltage of the low voltage electrical load means when the voltage of the storage elements is at its lowest. Along with this, a rectifying means and a smoothing circuit composed of an inductor and a capacitor are provided on the output side of the switching means to control the ratio of ON time and OFF time (dead time) of the switching means. As a result, a stable low-voltage power supply is constructed without being affected by changes in the voltage (SOC) of the storage element.",
