Question

The class E inverter as shown in Figure 7-1 operates at resonance and has Vs-48 V and R-10 Ω The switching frequency is fs- 20 kHz. Assume a quality factor Q-7. (a) Calculate the parameters and complete Table 7-1. Assume an ideal transistor switch the optimum values on inductor / the optimum value of capacitor C the optimum values on inductor Le the optimum value of capacitor Ce the damping factor δ the peak output voltage Vo for Vi= 12 V Irom G(ju)-.

Apply a pulse-voltage of 5V (peak) with a duty cycle of k- 0.304 Use any MOSFET (e.g. 2N6756) or IGBT that meet the voltage requirements. Run the simulation from 0 to 1.5 ms so that the steady-state condition is reached. Make sure that the transistor is turned on and operated as a switch PULSE(0 5V 0 0.1ns 0.1ns 12.24us 40us) 1.Plot the instantaneous output voltage vo(t) 2. Plot the instantaneous voltage across the transistor switch vr(t)
