Cov hlau melting rauv tuaj yeem pib, thiab muaj overcurrent thaum lub zog nce. Feem ntau ua rau:

① Lub nruab nrab zaus transformer puas los yog puas lawm,

② Lub inverter pulse transformer puas lossis puas lawm,

③ Inverter SCR muag muag lossis sib cuam tshuam,

④ Cov dej ntws ntawm cov thawj series capacitor ntawm qhov nruab nrab zaus transformer,

⑤ Lub tshuab hluav taws xob cua sov capacitor muaj qhov muag muag, thiab qhov rwb thaiv tsev ntawm lub nplhaib ntawm lub tshuab hluav taws xob lossis tooj liab tsis zoo hauv av lossis luv luv luv.
