Explanation: The most effective frequency range for pulse generator for optimum efficiency and component size is 20kHz. 10. Filter used in switching regulator’s are also as called
A. DC – AC transformers
B. AC – DC transformers
C. DC transformer
D. AC transformer
Answer:A
Explanation: The most effective frequency range for pulse generator for optimum efficiency and component size is 20kHz. 10. Filter used in switching regulator’s are also as called
A. DC – AC transformers B. AC – DC transformers C. DC transformer D. AC transformer
Explanation: Filter converts the pulse waveform from the output of the switch into a dc voltage. Since this switching mechanism allows a conversion similar to transformers, the switching regulators is often referred to as a DC transformer. 11. Which of the following is considered to be the most important components of the switching regulator?
