POWER-TAKING CIRCUIT, PARALLEL-TYPE PHOTOVOLTAIC COMPONENT CONTROL DEVICE, AND PHOTOVOLTAIC STRING POWER DISTRIBUTION SYSTEM

The present disclosure relates to a power-taking circuit suitable for use in conjunction with a bypass circuit of a photovoltaic component, a parallel-type photovoltaic component control device, and a photovoltaic string power distribution system. In embodiments of the present disclosure, the power-taking circuit includes a pump-type voltage clamped circuit configured to release and output energy to generate a first internal voltage in a case that the bypass circuit is turned on, and generate the first internal voltage according to an output voltage of the photovoltaic component and store the energy in a case that the bypass circuit is turned off; and a comparison circuit configured to generate a first control signal according to the first internal voltage so that the bypass circuit is controlled to be turned off or turned on according to the first control signal.
