Description

technical field [0001] The invention relates to a novel optical-storage integrated DC converter, which belongs to the technical field of DC / DC converters. Background technique [0002] In the traditional hybrid multi-port converter solution, the new energy micro power supply and energy storage unit are generally connected in parallel with the DC bus through their respective DC / DC converters, although this structure can solve the problem of energy storage unit balancing the power generation output of the micro power supply and improving the system performance. Power supply stability problem, but due to the parallel structure of DC / DC converter and DC bus bar, the energy storage system needs to perform two power conversions every time it charges and discharges electricity, resulting in problems such as waste of power energy and low utilization rate of power energy, and The parallel structure will also increase the system design cost and the complexity of the controller design....
