What is AC voltage controller and its application?
A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, triodes for alternating current, silicon-controlled rectifiers or insulated-gate bipolar transistors, which converts a fixed voltage, fixed frequency alternating current (AC) electrical input
What is AC voltage controlled?
AC Voltage Controller is a thyristor based device which converts fixed alternating voltage directly to variable alternating voltage without a change in frequency. AC Voltage Controller is a phase-controlled device and hence no force commutation circuitry is required. Natural or line commutation is used.
What does a voltage controller do?
A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions.
What are the two types of AC voltage controllers which one of these is preferred Why?
Phase angle control: Output voltage waveform is continuous but phase controlled. The type of AC controller which is highly preferred is Phase angle control, because it contains less ripple and discontinuities in output.
What are the different control strategies of the AC voltage controller?
In brief,an AC Voltage Controller is a type of thyristor power converter which is used to convert a fixed voltage, fixed frequency ac input supply to obtain a variable voltage ac output. The RMS value of the ac output voltage and the ac power flow to the load is controlled by varying (adjusting) the trigger angle ‘u03b1’
What are the advantages and disadvantages of AC voltage controller?
Thyristor based ac voltage controllers have high efficiency, flexibility in control and require less maintenance. 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.
