“…In accordance with the analysis in Ref. [10], when many harmonics are present in the system current, design should be performed with a Q of about 2, and when there are few harmonics and ripple voltage suppression is emphasized, design should be performed with a Q of about 4. In this paper we perform design with Q = 3.…”

“…In an SVC, the ripple voltage component superimposed on the output voltage after passage through the LCR filter must be reduced as much as possible, and the values of L and C must be designed as small as possible. A damping resistance R that does not reach resonance due to the effect of the harmonics included in the system current must also be designed [10].…”

In this paper, we propose a strategy for the design of the LCR filter in a series voltage compensator and investigate our method by performing simulations and experiments. In the proposed method, first, the inductance L f is derived from the ratio of the maximum amplitude of the ripple current to the amplitude of the fundamental current, which is denoted as {%I ri p }. Second, the capacitance C f is derived from the ratio of the ripple voltage to the fundamental voltage. Third, the resistance R is determined from the rate of decrease of the carrier frequency component and the settling time. C⃝ 2014 Wiley Periodicals, Inc.

Electrochemical machining (ECM) is a processing method for metals that uses a DC power supply and flowing electrolyte. In some cases, discharge occurs during ECM when the gap between the electrode and workpiece, whose distance is rather small, is filled with hydrogen generated via electrolysis. We attempt to utilize a DC inductor placed between the DC supply and the ECM load in order to limit di/dt of the short or discharge current, which damages both the electrode and workpiece. When the output current surges, that is, when discharge occurs, the output voltage is suppressed by the DC inductance. In this paper, we propose a method for designing a PWM rectifier to reduce the discharge current, establish a linear approximation model for use in the PWM rectifier, describe a control method of the PWM rectifier, and demonstrate the efficacy of the model via simulations and experiments.
