Linearization Research of Phase Shifting Triggering Thyristor and Its Application in Voltage Feedforward Control

用查表和线性插值计算相结合的软件方法给出了晶闸管移相触发调压器的输出电压与其导通角之间线性化途径。作为一个应用实例,在恒温水槽温度控制系统中加入电压前馈控制以抵消电网电压波动对控制质量的影响时,经线性化的晶闸管移相触发调压使电压前馈控制的作用更趋完善。

The output of voltage regulator with phase shifting triggering thyristor and its conduction angles are nonlinear. In this paper, the software method to combine checking table with linear interpolation gave it a linearization way. In a water thermostat system, as example, when using voltage feedforward control strategy eliminates the infection of voltage fluctuation for control character, the output of phase shifting triggering thyristor with linearization make the control action perfection.
