Abstract
A power conversion device for a photovoltaic system includes a first boost isolation DC/DC converter and a controller. The first boost isolation DC/DC converter includes a transformer, an input terminal of the first boost isolation DC/DC converter is connected to a first photovoltaic component, and an output terminal of the first boost isolation DC/DC converter is connected to a DC bus. The controller is configured to receive a bus voltage of the DC bus and a bus output current output by the first boost isolation DC/DC converter, and output, based on the bus voltage and the bus output current output by the first boost isolation DC/DC converter, a switch control signal that controls the first boost isolation DC/DC converter to perform maximum power point tracking control of the first photovoltaic component.
