| Abstract: | The shortcomings of Buck and Boost circuits applied in the maximum power point tracking(MPPT) circuit were analyzed,and a battery pulse charging circuit controlled by PIC microcontroller for stand-alone photovoltaic power generation was proposed.The circuit has one energy storage element,which can greatly reduce the volume of converter and the power losses.The experimental results indicat that the system reaches the MPPT function and can charge the battery with pulse. |
