The input impedance seen by the voltage source V S in the circuit of Figure 9.32 is and thus the circuit of Figure 9.32 can be replaced with the simplified circuit shown in Figure 9.33. Figure 9.33: ...

Most of these power supplies use a transformer to step down the voltage to a more usable level and also to provide some galvanic isolation to the low voltage circuit. But for circuits where weight ...

transformers create a natural dielectric boundary from the input to output circuits, and the input voltage levels are independent from the output voltages. Unfortunately, multiwinding magnetics are ...
