solution

three-phase thyristor converter is shown in the figure below. In the first part of the problem, assume the line inductance to be neglected. The line voltage rms value is 230V and 50Hz (sinusoidal). The load current is 10A Ts Ts (1) In the following waveform, from wt-0 to at-e, indicate which thyristors are conducting and the thyristor’s switching points Den bn Aa ot UNn (2) Find the equation for the average value of is a variable the dc voltage ve, where the firing angle a through the rectifier when the firing anglie is 3) Calculate the ac power passing 60 (apparent power t 4) Find the Ve loss due the the firing angle a
