What is a high frequency power supply?

The high frequency power supply to work piece depends upon the value of R and C. The smaller the product of R and C, higher is the frequency across the work piece. Sometimes spark gap oscillators are also employed to provide high frequency power supply.

Are high frequency power supplies available for ESPs?

The availability of high frequency power supplies for ESPs are discussed. Results of reliability measurements on a new transformer design show a meantime between failures exceeding 200 yrs. Fig. 15. LCC circuit diagram III. AVAILABILITY The availability of ESPs operating in power plants or in industrial processes is of great importance.

When were high-frequency power supplies introduced?

High-frequency power supplies (HFPS) were originally introduced on the ESP market in 1993 . An evaluation of the experiences gained during the first decade of operation was presented in . Many publications have been made since the introduction of this technology, some examples are [3-5].

Can high-frequency power supplies be optimized for electrostatic precipitators?

At higher power levels the efficiency and the operational temperatures are key design parameters. It is the objective of this paper to present recent findings on the optimization of design and operation of high-frequency power supplies for electrostatic precipitators. Specifically, operational efficiency and availability will be discussed.

Is high frequency power conversion a new technique for ESP energization?

P. Ranstad and K. Porle, “High frequency power conversion: A new technique for ESP energization”, Proceedings of the EPRI/DOE International Conference on Managing Hazardous and Particulate Air Pollutants, Toronto, Canada, August 1995.

Do high-frequency power supplies reduce dust emissions?

Abstract— High-frequency power supplies were originally introduced on the ESP market by ALSTOM (SIR) in 1993 [1, EPRI/DOE 1995]. An evaluation of the experiences gained during the first decade of operation was presented in [2, ICESP IX 2004]. It was found that the dust emissions were significantly reduced at the majority of the installations.
