Description
technical field [0001] The invention relates to a technology for stabilizing output voltage of a permanent magnet generator, in particular to a silicon-controlled rectifier for a permanent magnet three-phase AC generator using an embedded microcontroller. Background technique [0002] At present, in the power supply of aircraft, ships, automobiles, construction machinery, and wind power, the use of permanent magnet generators is becoming more and more common. The output voltage of the permanent magnet generator changes with the speed. Because of the large range of operating speed, the output voltage range is also large. When the speed is high, the output voltage is high, and when the speed is low, the output voltage is low. Sometimes there is a difference of 1-3 times. In order to stabilize the output voltage of the permanent magnet three-phase alternator, the current general adoption is: 1. Mechanical or electronic switch parallel connection short-circuit power discharge m...
