What are the two method of control in AC voltage controller?

The working principle of AC Voltage Controller is based on either of two methods: Phase Control or Integral Cycle Control. In Phase Control method, the phase relationship between the start of load current and the input supply voltage is controlled by controlling the firing angle of the thyristor.

What are the disadvantages of ac voltage controllers?

The disadvantage of ac voltage controllers is the introduction of harmonics in the supply current and load voltage waveforms particularly at low output voltage levels. Power Factor Control Power factor control, also known as correction of power factor, is the process of reducing the amount of reactive power.
