Is N N Vo V's Vo Vs LOAD LOAD Figure 1 It has been shown in lectures that from the equality of power generation and power consumption, and as far as the average input/output voltages and currents are concerned, the buck and boost converters' operation in CCM (continuous current mode) are similar to the operation of the ideal AC transformers. So these converters may be considered as "ideal DC transformers". A buck converter operates with a duty cycle D 0.4,...
