Evaluation of HV Power Source for ESP

Since the formal application of industrial ESP, our country has got great breakthrough in technology and wide application of it. As an important part of ESPs, High-voltage power source has gone through procedures as simulative control single-phase power source, constant-current power source, pulsed power source, three-phase HV power source, high frequency switch power source and HV contravene DC power source. For single field, one type of power source was used in the past. A few ESP manufactures begin to apply various types of HV power source on the same ESP in recent years. This article will analyze the advantages and drawbacks of HV power sources of ESP, give theoretic analysis and research for comprehensive use of various HV power source on the same ESPs.
