| description | The invention discloses a photovoltaic power generation interface system which comprises a photovoltaic power generation module, a mode setting module, a main circuit module and an energy storage module. The main circuit module uses a bidirectional half-bridge converter, the transmission power is small, the efficiency is high, and the conversion of charging and discharging modes of the photovoltaic power generation interface system is conveniently realized. Meanwhile, according to the control method of the photovoltaic power generation interface system, a single-chip microcomputer is adopted to directly generate the PWM signal, and the output of the photovoltaic power generation interface system can be adjusted by sampling the output of the main circuit module and then changing the duty ratio of the PWM signal; whether the photovoltaic power generation interface system works normally or not can be judged according to the selected working mode and the actual working state, and protection is provided for the ph |
