In an alternating source of frequency 50hz
WebAn alternating current of frequency 50 Hz has a maximum value of 100 A. Calculate (a) its value 1/600 second after the instant the current is zero and its value decreasing thereafter (b) how many seconds after the instant the current is zero (increasing thereafter wards) will the current attain the value of 86.6 A ? alternating current 1 Answer WebApr 1, 2024 · We have developed and implemented in the microcontroller a unipolar PWM control that generates this command sequence. The generation of this command sequence is based on the comparison of a sinusoidal reference signal of frequency 50 Hz (the desired signal at the output) and a high-frequency triangular carrier.
