摘要
针对双频变频无刷同步发电机电压稳定调节的要求,提出了以TL494集成脉宽调制器为核心的脉宽调制(PWM)励磁调节技术,研制了中频(400 Hz)和工频(50 Hz)的自动电压调节器。
Aim at the requirement of the voltage stabilization for dual frequency(50 Hz and 400 Hz) and variable frequency brushless synchronous generator,putting forward the pulse-width modulation(PWM) excitation regulating technique which core is TL494 integrate pulse-width modulator,and developing two kinds of automatic voltage regulator both 50 Hz and 400 Hz.
