In a variable switching frequency control scheme, it is challenging to design the voltage source inverter (VSI) parameters without knowing the maximum and minimum switching frequencies. The switching frequency variation depends on the system parameters. Therefore, the expression for frequency variation in one inverter topology does not hold in other topologies. The design of hysteresis current controlled four-leg shunt active power filter (APF) requires the switching dynamics analysis to ensure satisfactory performance of the inverter. In this study, a detailed analysis on the switching dynamics of hysteresis current controlled four-leg VSI and design of various inverter components for compensating unbalanced and nonlinear loads are presented. The results obtained from these analyses can be used in any applications involving hysteresis current controlled four-leg VSI. These results are supported by detailed simulation studies conducted on a three-phase four-leg shunt APF system using Matlab/Simulink. The theoretical studies and design of passive components are also verified by conducting experiments on a prototype of four-leg shunt APF developed in the laboratory.

“…There are many current control methods for the VSCs. The hysteresis current control method based on instantaneous current error is preferred because of its accuracy, fast dynamic performance and simplicity [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. However, the switching frequency in hysteresis current control method depends upon the system parameters, operating conditions and its mode of operation.…”

“…However, the switching frequency in hysteresis current control method depends upon the system parameters, operating conditions and its mode of operation. Another drawback of the hysteresis current control method is the variable switching frequency over the fundamental frequency power cycle [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The instantaneous switching frequency is an important variable of the converter for safe and smooth operation of the switching devices [13][14][15][16][17]25].…”

“…It is also required to know the variation of switching frequency over the power cycle [13][14][15][16][17]25] and its dependence on the various system parameters. The maximum switching frequency estimation is important for suitable selection of power semiconductor switch ratings used in the VSCs, the average switching frequency estimation helps in calculation of converter switching losses and the minimum switching frequency gives the information about harmonic distortions.…”

This study presents a unified time-domain formulation of switching frequency for hysteresis current controlled AC/DC and DC/AC grid connected converters. It is shown that the generalised expression of switching frequency obtained can be used for any mode of operation of the converter based on phase relation between the reference AC current and grid voltage. The presented analysis provides information of maximum, minimum and average switching frequencies for all modes of the converter operation. The analytical results derived under different configurations are verified through the experimental results obtained using FPGAbased implementation of the controller for the converter. The applications of the results are shown on the three different singlephase systems operating in current control mode: (i) static synchronous compensator, (ii) boost rectifier and (iii) grid interface of wind-turbine system. The results of switching operations in these applications are verified using simulation studies performed in power systems CAD/electromagnetic transients including DC (PSCAD/EMTDC) software.

“…Therefore, this series PFC circuit has the potential for low-cost single-phase PFC applications. The common control scheme for the high-frequency switch S H is the hysteresis control [10]. The variable frequency property of hysteresis control and wide spreading of spectrum are challenges for the filter design.…”

This letter proposes a hybrid modulation scheme for the average current control (ACC) of the series-type single-phase power factor correction (PFC). The series PFC is a newly developed harmonic correction method for single-phase diode rectifier. It is composed of a hybrid full-bridge inverter and is in cascade between the dc terminal of the diode rectifier and the dc load. When the conventional ACC is applied, due to the large duty-ratio variation at the low-frequency transition points, the line current waveforms exhibit large distortion at the low-frequency switching points. A hybrid scheme, which combines the leading-edge and the trailing-edge modulation, is developed to overcome this problem. The reference signal selection and control logic design are discussed and implemented. Experimental results show that the proposed hybrid approach is able to reduce the harmonic distortion in the line current significantly, as compared with the conventional ACC control.
