The invention belongs to the technical field of rectifiers, and particularly relates to a method for improving the electrical performance of a rectifying device, which comprises the following steps of: centrally leading out an output negative electrode electrically connected with a secondary winding between output ends on two sides of the secondary winding of a transformer, respectively connecting rectifying modules on the output ends on the two sides, and connecting the rectifying modules on the two sides with an inductor, so that the output positive electrode of the rectifying device is led out of the inductor. According to the method provided by the invention, the output negative electrode is arranged in the middle between the output ends on the two sides of the secondary winding of the transformer, and the output positive electrode is led out by connecting the inductor to the rectification modules on the output ends on the two sides in parallel. Therefore, the current uniformly flows to the rectification modules on the two sides and then flows to the load through the inductance gathering output, the temperature difference of the rectification modules on the two sides is effectively reduced, the damage speed of the rectification modules is wholly slowed down, and the service life of the rectification device is prolonged.
Description
technical field [0001] The invention belongs to the technical field of rectifiers, in particular to a method for improving the electrical performance of a rectifier. Background technique [0002] As a kind of electrical equipment that changes the voltage, frequency, phase number and other power or characteristics of the power system, the rectifier has been widely used in the transportation industry, manufacturing industry, etc., such as the shipping industry and the electroplating industry. Some rectifiers usually have inverter radiators and rectifier radiators arranged up and down in their cabinets. The inverter radiators and rectifier radiators basically span the entire cabinet, and are located on the lower side of the rectifier radiator. Two transformers arranged in series laterally on the sides of each transformer are connected to the Schottky group (rectifier module) attached to the bottom of the rectifier radiator. Due to the layout of the above components, the flow to...
