Abstract

The invention discloses a power supply circuit with the function of reducing power consumption of an anti-reverse diode, comprising a DC power supply, a voltage equalizing unit, an inverter unit, a conversion unit with a transformer, an anti-reverse unit, a current sensor and a controller. When the power supply circuit of the present invention is working, the controller controls the conduction of the MOS transistor when the current sensor detects that a current flows through the diode, thereby bypassing the diode, because the conduction voltage drop of the MOS transistor is smaller than the conduction voltage drop of the diode Therefore, the problem of large energy loss in the existing power supply circuit with anti-reverse diodes can be solved, and the power consumption of the diodes can be reduced.

Description

technical field [0001] The application relates to the field of solar power generation, specifically a power supply circuit with the function of reducing power consumption of anti-reverse diodes. Background technique [0002] For the ground power station, in order to increase the utilization rate of the land and the metal support, consider that there is no shelter between the working window components during the sunshine time of 9:00-15:00, and generally use 2 to 3 rows of components to install on the support. However, outside the designed sunshine time window, shadow occlusion is unavoidable. In roof power plants, especially metal roof power plants, there are usually taller buildings around them. Especially for factory buildings that are generally designed with a herringbone structure on the north and south sides, there will be an air tower in the middle. Considering the utilization rate of the roof, the shading analysis on the north side will be done to the greatest extent...
