a new output structure for class e power amplifier (pa) is proposed in this paper. a series lc resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. this resonator causes low impedance at the second harmonic. the output circuit is designed to shape the switch voltage of the class e amplifier and lower the voltage stress of the transistor. t...

This paper presents an efficient algorithm to solve the multi-objective (MO) voltage control problem in distribution networks. The proposed algorithm minimizes the following three objectives: voltage variation on pilot buses, reactive power production ratio deviation, and generator voltage deviation. This work leverages two optimization techniques: fuzzy logic to find the optimum value of the r...

In this paper, a comparative study on the subject of robust control of dc/dc PWM converters is presented. Considering a wide range of possible changes for the converter’s operating conditions, robust control of dc/dc PWM converters using some state of the art robust controllers i.e., ∞ H , μ , and fuzzy controllers is studied. The system under study is a CUK converter as a non-linear, variable ...
