This paper focuses on discussing the type selection, analysis and optimization design of the snubber in switching power amplifier (SPA). Based on the principle analysis of the selected snubber, its design is summarized as a multi-objective optimization problem (MOP). Then the proposed MOP is solved by the modified nondominated sorting genetic algorithm II (MNSGA-II), which is constructed by introducing...
An inverter designed for protective relay testing (PRT) purpose is modeled and analyzed in frequency domain, which is named as PRT inverter. By introducing the concepts of ldquobiased on-timerdquo and ldquotime-voltage transfer coefficientrdquo, a modified model is proposed, which realizes the linear transition from duty cycle to output voltage and breaks the frequency limitation of the linearized...
This paper intends to establish the interactive communication networks intensity of its information resources in the small world, applying ant colony algorithm and eventually to design information resources interactive mechanism, which based on the echo model of the TMA (TELECOMMUNICATION MARKET AGENT). The information resource communication and transmission of TMA is to promote the information resourcepsilas...
An electrical fault-waveform regenerator (EFWG) is proposed in this paper originally, including its hardware structure and software flow chart. And the EFWG is mainly relying on a power amplifier (PA) to regenerate the electrical fault waveforms recorded by fault recorders (FR), so a digital closed-loop modification technique (DCLMT), which is distinct from the predistortion technique (PDT) widely...
