Description

technical field [0001] The invention relates to the technical field of electronic power, in particular to a power control circuit, a method, an energy router, a photovoltaic device, and an energy storage device. Background technique [0002] Due to the limitation of the current and voltage of electronic components, the existing single circuit topology of the energy router has a small power level, and the current ripple of the circuit is relatively large. The multiple power control circuit topology can effectively reduce the circuit current ripple and improve Circuit power rating. In practical applications, when the power is low, the existing multi-energy router circuit topology can reduce the current ripple at low power, but it cannot adjust the multiplicity of the power control circuit according to the transmission power of the energy router, which may easily cause unnecessary power failure of the device. loss. [0003] Aiming at the problem in the prior art that the mult...
