9. NUMERICAL RESULTS
Fig. 5 and Fig. 6 show the output voltage and input current waveforms in the time domain). It can be observed that the peak output voltages and currents for the normal case and other faulty cases are very similar, though there is a slight dif-ference in the peak and a small phase shift, in case of change in the secondary capacitor and the capacitance between the primary and secondary windings. Hence, it is difficult to quan-titatively describe the difference in the current and voltage waveforms by visual inspection alone. However, if trans-admittance in time domain is obtained, the difference is more apparent for the different cases, as shown in Fig. 7, especially in case of a change in the secondary capacitor and the capaci-tance between the primary and secondary windings.
