A method is disclosed for controlling the operating of a consumption appliance by way of a selector switch controlled by an energy saving device connected to a management center. The consumption appliance is kept in its default power mode, until receiving, by the energy saving device, an authentic secured control message sent by the management center. This message includes a command onto the mode in which the consumption appliance has to be switched. A counter is initialized with an initialization value before to be triggered. The consumption appliance is switched in the mode indicated by the command, either until the counter has reached a threshold value, or until receiving another authentic control message. If the counter has reached the threshold value, then the consumption appliance is switched in its default power mode. If another authentic secured control message has been received, then returning to the step of initializing the counter.

The disclosure describes a solar home system that may be used for the following purposes in the household: lighting, mobile phone and other electronic device charging through Universal Serial Bus (USB) ports, receiving television signal through digital TV signal, receiving internet information through the wireless network signal and powering electronics through an inverter. The present invention is very beneficial for households who do not have access to electricity from the electricity grid, households that have unreliable access to electricity, or households that choose not to utilize electricity directly from the grid.

A resonant transformer connected between a ground terminal and elevated terminal draws current from the earth's electric field through a primary winding of the transformer. An impulse generator applies a high voltage impulse to the primary winding of the resonant transformer to cause current to flow from the ground terminal through the primary winding. The flow of current through the primary winding of the resonant transformer induces a current in the secondary winding, which may be converted and filtered to a usable form, e.g. 60 Hz AC or DC.

A drive system comprises a DC-DC converter that is arranged to receive an input voltage from a battery having a nominal battery voltage. The DC-DC converter has a first mode of operation in which the DC-DC converter generates a regulated output voltage from the input voltage and supplies the regulated output voltage to a load, and a second mode of operation in which the DC-DC converter is by-passed such that the input voltage from the battery is supplied to the load. A controller is arranged to compare the input voltage to a threshold voltage that is less than the nominal battery voltage. The controller operates the DC-DC converter in the first mode when the input voltage is less than the threshold voltage, and operates the DC-DC converter otherwise.

An energy-efficient power supply system is provided, which includes: a solar electric generating device, an energy storage device, a voltage conversion device, a control device, and a plurality of DC voltage connecting ports. The voltage conversion device provides a DC voltage to the plurality of DC voltage connecting ports. The energy-efficient power supply system does not have any AC voltage connecting port. The energy storage device acquires AC electric power by purchasing from a power grid system via an AC-to-DC voltage converter and a smart electric meter, converts the AC electric power into DC electric power, and stores the DC electric power.
