“…Theoretically, it is not difficult to extensively apply some harmonic analysis methods to interharmonics measurement by the concept of Fourier transform [15][16][17][18][19][20][21][22][23]. In a practical circumstance, however, there are still many concerns as follows [24]: (i) It is not easy to extend to low power analogue model and time-domain model.…”

Recently, an increasing use of power electronic facilities in industry has produced considerable harmonics and interharmonics in power systems. The power supply quality is therefore seriously threatened. The discrete Fourier transform (DFT) is currently the most important tool in signal analysis. However, a misapplication of DFT may result in incorrect outcome because of some inherent limitations such as spectral leakage or aliasing effect etc. The existing interharmonics even raise more difficulty in signal analysis than harmonics. To overcome this dilemma, this study develops a strategy of leakage energy allocation method for both stationary and non-stationary interharmonics identification. The proposed algorithm can regain its original interharmonics amplitude by restoring all spilled leakage energy, and also finds its individual frequency component according to the distribution of spilled leakage energy. The performance effectiveness of the proposed approach is verified using the numerical examples in terms of reliability, rapid response and high-precision performance.

“…And that the digital controller has been designed with deadbeat control theory to achieve fast dynamic response [7,8]. Except for deadbeat control, the control approaches involve PID control [9,10], repetitive control [11,12], instantaneous feedback control, sliding mode control and so on [13,14].…”

Abstract-Novel circuit topology and advanced control technique of inverter are research focus for programmable AC power source. An improved dual buck half bridge inverter topology is introduced and the central symmetrical pulse width modulation mode is proposed to double the output current ripple frequency. High output precision can be achieved by optimizing the output waveforms of inverter. Then, a hybrid digital control scheme combining PID control with repetitive control as well as inductance compensation deadbeat control is presented for the closed loop voltage regulation of the mentioned inverter. Besides, an inductance saturation characteristic mathematic model is established for accurate simulation. Simulation results show that the theoretical analysis of the special switching sequence and hybrid control scheme is true.

Abstract-In this paper, the effect of switching surface on sliding mode control of a single phase inverter is studied. Capabilities of three switching surfaces in chattering elimination, THD reduction and steady state error improvement are compared. The performance of these switching surfaces has been investigated through simulation. Simulation results show that after chattering improvement by adding first integral term, adding second integral term is not advisable.
