Description

technical field [0001] The invention relates to the technical field of AC power supply, in particular to a system and method for generating evenly distributed twelve-phase discrete phase-modulated single-phase voltage. Background technique [0002] The commonly used power supply mode in the power system is three-phase or single-phase AC power supply, and its output voltage has few phases, and it is fixed and cannot be adjusted. [0003] The conventional phase-adjustable voltage output device is a signal generator, whose output phase is generally adjusted continuously, and it is difficult to control the specific output phase; its output frequency is generated by its internal oscillator circuit or digital signal synthesis, and it is difficult to strictly follow the external signal (voltage ) frequency, and is affected by the (parameter) stability of the system oscillator and other components and the working environment temperature; the phase adjustment through the phase shift ...
