What are the main advantages of using switcher type power supply?
A. Line voltage is directly rectified and filtered to produce a high dc voltage, components are much smaller and lighter weight, can provide much better efficiency.
B. The transformed voltage is directly rectified and filtered to produce a high dc voltage, components are much smaller and lighter weight and can provide much better efficiency.
C. They use laminated steel transformers which are more efficient.
D. Using a center tapped transformer secondary allows fewer rectifiers to be used.
