Insimbi ukuncibilika kwesithando somlilo ingaqalwa, futhi kukhona i-overcurrent lapho amandla engeziwe. Izimbangela ezijwayelekile:

①I-intermediate frequency transformer yonakalisiwe noma ayinasici,

②I-inverter pulse transformer yonakalisiwe noma inesici,

③I-Inverter SCR ukuwohloka okuthambile noma okuphakathi,

④Ukuvuza kwe-primary series capacitor ye-intermediate frequency transformer,

⑤I-capacitor yokufudumeza kagesi inokuqhekeka okuthambile, futhi ukufakwa kwendandatho yesithando somlilo noma ibha yethusi akusekelwe kahle noma akufushane kancane.
