Abstract

The invention discloses a power conversion device based on a switched reluctance motor. The power conversion device comprises the switched reluctance motor, a power converter, a supercapacitor and a battery pack. The switched reluctance motor and the power converter are connected to an AC power source. The supercapacitor is connected to the switched reluctance motor and the power converter througha first bidirectional DC / DC. The battery pack is connected to the switched reluctance motor and the power converter through a second bidirectional DC / DC. A converter of the switched reluctance motorand the power converter is an asymmetric half-bridge power converter. The first bidirectional DC / DC and the second bidirectional DC / DC are arranged at the front end of the asymmetric half-bridge powerconverter. The power conversion device improves the efficiency of a switched reluctance motor drive system, avoids the influence of frequent charging and discharging on a battery life, prolongs the service life of the battery, and reduces pollution caused by battery charging on a power grid.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a power conversion device based on a switched reluctance motor. Background technique [0002] With the rapid development of society and economy, the use of automobiles continues to increase, and the exhaust emissions of fuel vehicles have become the main source of air pollution. Electric bicycles have developed rapidly because of their advantages of convenience, energy saving, pollution-free, and low price, and have gradually become the main means of transportation for people to travel short distances. Switched reluctance motors are often used as drive motors for electric motorcycles and electric bicycles because of their small starting current, large starting torque, and good low-speed performance. Due to the battery power supply method, the mileage of electric motorcycles is greatly limited. Electric motorcycles often drive in urban areas and often ...
