Question

In the integral cycle control of ac voltage controller, is the load is on for n cycles and off for m cycles, then the periodicity is given by? Consider the output is sinusoidal.

(a) m/2π(m+n)

(b) n/2π(m+n)

(c) m/π(m+n)

(d) n/π(m+n)

This question was posed to me in unit test.

This is a very interesting question from AC Voltage Controllers-2 topic in division Voltage Controllers of Power Electronics

Answer 1

The correct option is (b) n/2π(m+n)

Explanation: Over a complete cycle of 2π x (on cycles + off cycles) the power is delivered for n cycles.

Hence, P = n/2π(m+n).
