Development of the Klystron Modulator Using a High- Voltage Inverter Power Supply*

چکیده
The existing klystron modulator in the Linac use a 60 Hz high voltage power supply and adopt traditional L-C resonant charging scheme with De-Qing circuit. The stability of the output high voltage is not satisfactory especially when the AC line voltage fluctuations. If an inverter power supply is used as a HV generator, it will just meet the demands A high frequency inverter switching makes the overall system size small. The command-charging feature can guarantee the high reliability of switching function. In order to increase the stability, operating reliability and comply with the PLC (programming logic controller) and touch screen control system of PLS, an upgrading works is now in progress. This paper will discuss some inverter power supply design considerations and show the test results.

Analyses of Klystron Modulator Approaches for Nlc
Major changes to the Next Linear Collider (NLC) design were facilitated by the experimental testing of the 75 MW X-band klystron at a 3.0 μsec pulse width 1 and new component development allowing the delay line distribution system (DLDS) to operate with eight bins instead of four. This change has a direct effect on the design of the klystron modulator. The general approaches, which are being st...
متن کاملInstallation and Operation of New Klystron Power Supply with Fast Solid-state Switch for Klystron Protection at the Photon Factory Storage Ring
In the 2.5-GeV Photon Factory (PF) storage ring at KEK, one of the klystron power supplies was upgraded during a summer shutdown in 2003. The new power supply can provide a DC high voltage of up to 45 kV with the maximum current of 9 A. To protect the klystron under sparks, a noble solid-state switch was incorporated. This paper describes the design and the performance of the new power supply. ...

In this paper a two-phase supply modulator suitable for envelope tracking power amplifier is presented. The designed supply modulator has the linear assisted switching architecture. Two-phase architecture is used in order to reduce the output switching ripples. The proposed architecture uses hysteretic control instead of pulse width modulation (PWM) which significantly reduces the circuit compl...
متن کاملDesign and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...

This paper introduces a new design of penternary inverter gate based on graphene nanoribbon field effect transistor (GNRFET). The penternary logic is one of Multiple-valued logic (MVL) circuits which are the best substitute for binary logic because of its low power-delay product (PDP) resulting from reduced complexity of interconnects and chip area. GNRFET is preferred over Si-MOSFET for circui...
