WebbGiven, that the thyristor has a conducting time of 150μseconds. Calculate the chopping frequency. Solution − The chopping frequency f f = 1 T Where T – Chopping time period = T O N + T O F F Given − V S = 150 V V 0 = 450 V T O N = 150 μ s e c V 0 = V S ( T T − T O N) 450 = 150 T T − 150 − 6 T = 225 μ s e c Therfore, f = 1 225 ∗ 10 − 6 = 4.44 K H z WebbCERN Document Server

WebbThe full-wave rectifier can be constructed in 2 ways. The first method makes use of a centre tapped transformer and 2 diodes. This arrangement is known as Center Tapped Full-Wave Rectifier. The second method uses a normal transformer with 4 diodes arranged as a bridge. This arrangement is known as a Bridge Rectifier. Webb3 apr. 2024 · Light Dimmer Circuit Using Triac.
