“…In Fig. 1, considering the high switching frequency and neglecting harmonic components around switching frequency, the single-phase inverter can be equivalent to a proportional power amplifier K PWM (pulse width modulation) (normalised as 1) [25], and the voltage of arm-bridge u b can be replaced by reference voltage u i .…”

Parallel multi-inverter modules are characterised by expandable output power and improved reliability. A current-sharing control scheme has to be employed to achieve equally load current sharing of paralleled inverters. At present, circulating active/reactive power are applied to control the voltage in some current-sharing control schemes; however, the size and weight are increased owing to the extra inductor. In this study, the concept of virtual circulating impedance is proposed and introduced into current-sharing control scheme to achieve ideal performance without increasing size and weight in multi-inverter modules in parallel. The mathematical model of circulating impedance is established and the relationship between the phase and the amplitude of circulating current, the phase of inverter module's output reference voltage is decoupled. Simulation and experimental inverter modules are built and operated in parallel system. The results of simulation and experiment verify that the current-sharing control scheme based on circulating impedance is available and efficient.

“…However, most researches about this topic usually focus on 50 Hz application. With the development of the concept of the 'all electric aircraft' and the 'more electric aircraft', more and more researchers start to study the APF applied in the aircraft EPS to resolve the power quality issues [15][16][17][18][19][20]. In [15,16], a system model of variable-speed constant-frequency EPS of 90 kVA is built.…”

“…Fundamental and harmonic components of 400 Hz system could be estimated in a high speed. In [19], a multi-resolution-based DSP control strategy is applied in the aeronautical APF, to reduce the calculation time and increase the detection accuracy and speed. Moreover, one-cycle control and space vector control have been used in the aeronautical APF in [20].…”

To fulfill the high reliability of the aeronautical application, a novel three-phase four-wire shunt active power filter (APF) is proposed in this study. In this proposed configuration, traditional phase-leg which is composed of two power switches is replaced by the novel leg composed of one power switch and one diode. The annoying 'shoot-through' phenomenon is eliminated by using this novel configuration. Meanwhile, better efficiency and better performance brought by this novel configuration benefit the improvement of the compensation performance. Moreover, operation principle of the APF is analysed in detail; current control strategy and the voltage balance control strategy for the split-capacitor topology are studied as well. Finally, a prototype with the compensating capacity of 3 kVA is designed. Simulation and experimental results are shown to confirm the validity and feasibility of the novel aeronautical APF.
