CONSTITUTION:PWM waveform pulse pattern data is output from pulse pattern generating means 5 in response to the number of carrier pulses, the pattern data is converted by pattern data converting means 6 in response to an angular frequency command, and applied to a PWM waveform calculator 7. The...
Given the T-FF Circuit (left), complete the timing waveform diagram in Figure 1 (right) Calculate the ratio of Ra/Rq for (a) a sine wave, (b) a saw-tooth profile, (c) a square wave. 2. The synchronous generator has an efficiency of 98.4% when it delivers an ...
The sinusoidal and the triangular waveform phase detectors are the most commonly used ones in PLL systems. With the advancement of digital technology, a triangular PD can be constructed relatively easily with a combination of simple hard limiters and an XOR gate. Furthermore, when the input ...
