performed using an identical circuit, but the input voltage was 28 V, as opposed to 24 V in the rst simulation. The output voltages of both simulations are shown in the graph of Fig. 7.9. These two simulations show two major drawbacks of this simple circuit. The rst is the relatively high output impedance that results from the output lter. The second is the inability to regulate the output voltage against input voltage

Improving the sine-wave power circuit
Both of the weaknesses of the simple circuit shown in Fig. 7.7 can be easily overcome. The circuit in Fig. 7.10 uses a sine reference voltage, V(5),
