Abstract
The high frequency and high voltage capacitor was designed and tested and produced with precision technology. The film winding machine was installed and installed to produce new designed capacitors. By winding capacitor core, MPP (Metalized Film on Propylene Film) and PP (Propylene Film) or Aluminum film were feed together in multi-layers into the roll with very adjusted and controlled tension force. By testing to analysis of new designed various capacitors with different tension methods. The resonance frequency and allowable frequency range and durable high voltage of all new designed capacitor core roll were tested. The test result with prototype roll showed allowable frequency of 700 KHz and 450 Volt AC. They were approved enough proper performance by the detailed test procedure to be applied for high power induction heater LC circuit of industrial heating facilities.
