Improvement of Waveform Efficiency Using a Compensation Circuit
نویسندگان
چکیده
In order to improve the efficiency(usable RF to total pulse) of a klystron modulator, a system using a solidstate compensation circuit has been developed. This system remarkably improves a flat-top and flatness of the output waveform of the modulator by means of waveform synthesis. This paper presents the design and specifications of the compensation circuit and the results of a preliminary test using a line-type modulator.

Ultra-Widband Distributed Amplifier Using Loss Compensation Technique on Both Input and Output Circuit
In this paper, we analyze a distributed amplifier based on input/output attenuation compensation. The analysis is carried out for a HEMT transistor; and a constant-k section filter is used to calculate the amplifier’s characteristics such as attenuation factor, phase constant and gain. The proposed design approach enables us to examine the tradeoff among the variables, which include the type an...
متن کاملA New Strategy for Simultaneous Compensation of Instantaneous Reactive Power and Harmonics of Non-Linear Loads (RESEARCH NOTE)
This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...
