“…Using the double integral Fourier analysis method [17], the output ac harmonic currents cancellation effect of interleaving for a system of N parallel three-phase VSCs has theoretically been confirmed [13]. The impact of the non-conventional interleaving is also discussed in [15,18,19] and used in [16]. In summary, the previous work discussed above mainly focuses on symmetric interleaving and the impact of interleaving on system harmonic voltages and currents.…”

“…For example, it is very difficult to study the impact of interleaving on the circulating current and the relationship between the harmonic currents reduction, especially if more than two VSCs are involved in the paralleling system. Recently, people started to study the impact of interleaving on a paralleled three-phase VSC system in frequency domain [13,14,15,16]. Using the double integral Fourier analysis method [17], the output ac harmonic currents cancellation effect of interleaving for a system of N parallel three-phase VSCs has theoretically been confirmed [13].…”

Recent years have seen the proliferation of electronic devices that require multi-phase power converters to provide heterogeneous power rails to different systems. Typical systems will utilize symmetric interleaving as a method of reducing the input current ripple for the power converter. Asymmetric interleaving is a method of control that allows for a further reduction, and in some cases complete cancellation, of this input current ripple. This work looks at some of the challenges for a practical implementation using digital control, and provides results to quantify this improvement. This work demonstrates a control algorithm implementation capable of achieving nearly 3x reduction in the input current ripple via the asymmetric interleaving method.

“…For such interleaved-paralleling concepts, the circulating current between the paralleled threads could be significant [22] [23]. It appears as additional current ripples on the converter, which increase the current and thermal stress of the converters.…”

in this paper, a high-performance 22 MW/ 27 MVA test bench using pumpback topology is introduced for testing electrical machines. It proposes a cost-effective concept that works reliably even with a weak grid. A paralleling concept of two three-level IGCT converters is presented. It generates a five-level pulse pattern with low harmonic distortion at 600 Hz carrier frequency and 80 Hz load frequency. The selected magnetic device minimizes the circulating current, which ensures the full power utilization of IGCT converters. Moreover, the control concept works reliably at 7.5 times of carrier-to-load frequency ratio, while there is a sine filter and a variable-frequency transformer between the converter and load machines. This test bench has been experimentally validated at the customer site.

In this paper, three control schemes with variable switching frequencies are proposed and analyzed for the paralleled voltage-source inverters (VSIs) fed permanent magnet synchronous motor (PMSM) drive. The proposed schemes could be applied in the low-speed operation region of high-power drive system, where the frequency modulation index is high. Firstly, the field-oriented control (FOC) with phase-shifted chaotic space vector modulation (SVM) under synchronous frame and the FOC with phase-shifted chaotic sinusoidal pulse-width-modulation (SPWM) under stationary frame are proposed for the paralleled VSIs fed PMSM drive. The proposed phase-shifted chaotic PWM schemes not only eliminate specific switching harmonics completely but also suppress all remaining switching harmonic peaks in the spectrum. The avoidance of inherent circulating current is also considered in designing these two schemes. Secondly, the direct torque control (DTC) for the paralleled VSIs fed PMSM drive is proposed with circulating current suppression. Besides inheriting the advantages of DTC, the output currents of paralleled VSIs are kept balanced. The working principles of these three methods are presented in detail. Experimental results on a laboratory prototype are given to verify the validity of the three proposed control schemes for the paralleled VSIs fed PMSM with variable switching frequencies.
