Description

technical field [0001] The technology relates to a DC motor and its driving device, in particular to a dual-voltage control switched reluctance motor and its dual-voltage control driving device. Background technique [0002] At present, the control of switched reluctance motors adopts a single DC voltage, and there are three control methods, namely: angle position control, current chopping control and voltage chopping control. DC chopping is to convert a fixed DC voltage into a variable DC voltage, also known as DC / DC conversion. The basic idea of ​​chopping DC with a chopper is: if you change the operating frequency of the switch, or change the time ratio of the DC current on and off, you can change the average value of the voltage and current applied to the load. Most of the above control methods are commonly used in the prior art, such as speed control of DC motors, switching power supplies, and the like. The DC chopper uses power components to properly cut the fixed vo...
