A genetic algorithm and Taguchi method were used to optimize parameters for the residualcurrent device (RCD) snubber circuit of a DC-DC flyback converter. The most suitable algorithm was determined by using test functions to compare performance in three multi-objective optimization methods: non-dominated sort genetic algorithm-II (NSGA-II), multi-objective particle swarm optimization (MOPSO), and multi-objective differential evolution algorithm (MODE). Comparisons of coverage rate, distance between non-dominant solutions, and maximum walking distance showed that NSGA-II was superior to both MOPSO and MODE. Therefore, NSGA-II was used to obtain parameter values for the RCD snubber circuit. However, practical application of the parameter values was limited because the values could not meet the specifications required for real-world circuits. Thus, the parameter values obtained by NSGA-II were used in further factor-level experiments performed by Taguchi method. The experimental results indicated that, compared to previous design methods, the proposed NSGA-II and Taguchi method obtains better parameter values for the RCD snubber circuit.INDEX TERMS Multi-objective optimization, Taguchi method, RCD snubber circuit.

KEYWORD: switching power amplifiers; quasi-PID control method; single neuron; adaptive control method; protective relay test devices ABSTRACT: Protective relay test devices (PRTDs) are indispensable tools for testing protective relays and other security and automatic equipment. To promote test qualities, it is required that modern PRTDs be able to adapt to different loads, time-variant system parameters, random disturbances and fault waveforms containing various frequency components and nonperiodic components so as to ensure the accuracies of output waveforms, and this is directly determined by the performance of power amplifiers (PAs) adopted by PRTDs. Linear PAs (LPAs) are generally the preference choices, considering the difficulties in controlling the tracking accuracies of switching PAs (SPAs). Except that, however, SPAs have many advantages over LPAs. This paper presents an effective control method, named single-neuron quasi-PID control method, to improve the tracking accuracies of SPAs to make their applications in modern PRTDs feasible. Experiments show that the mean square error of this control method is less than 0.15%, meaning that the accuracy requirement of modern PRTDs is satisfactorily fulfilled. And the computational complexity of this control method is small and so it is very suitable for realization on lowperformance microprocessors.

Abstract-P and PI control methods are widely used in the closed-loop control of the inverters in various power electronic equipment. However, PID control method is barely adopted. In this paper, from an in-depth analysis of the operation and control processes of pulse width modulation (PWM) inverter, it is verified that PID control method is not suitable for inverter control. And the theoretical process gives birth to a new control method, which is similar but not identical to PID control method, therefore, it is named as pseudo-PID control method. For fundamentality and generality, the pseudo-PID control method is derived from the single-phase PWM inverter, which is the basis of threephase or multilevel inverters. To verify the performance of the pseudo-PID control method, it is applied to a single-phase PWM inverter for relay testing. The simulation and experimental results demonstrate that with the aid of pseudo-PID control method the accuracy of the output current of the inverter is already comparable to that of the linear power amplifier (LPA), which makes the application of inverter in relay testing feasible. Considering the higher efficiency and simpler structure of the PWM inverter, it can make the relay testing device more cost-effective.
