Abstract
The present invention relates to an energy supply circuit for instantly supplying power without a power converter and an electronic device which operates only when energy is supplied from an energy source using the same. An energy supply circuit without a power converter according to the present invention comprises: an energy extraction unitfor generating power from an energy source; and output unitfor supplying power to an external electronic circuit; a switch unitinterposed between the energy extraction unit and the output unitto connect an output end of the energy extraction unitto the output unitwhen switched on; and a maximum power point tracking control unitfor generating an open/closed signal for opening or closing the switch unitaccording to the voltage and current of the energy extraction unit. The present invention has a technical feature wherein a turn-on point of the open/closed signal comes at a time when the output end voltage of the energy extraction unitis Vh, and a turn-off point comes at a time when the output end voltage of the energy extraction unitis Vl. Accordingly, the present invention has a simple configuration, low manufacturing costs, has no energy loss due to the power conversion, and has no reduction in life due to charging and discharging of an energy storage device.
