The article presents elaborated technical suggestions for increasing reliability of electrical equipment agro-industrial complexes. analysis the already known ways measuring electric capacitance is carried out and it demonstrates necessity withdrawing a capacitor from working circuit sufficient accuracy determining capacitance. urgency developing method without removing а to reduce average reco...
For the two-stage single-phase converter, including power factor correction (PFC) ac-dc converter and dc-ac inverter, a second harmonic current compensator (SHCC) can be introduced to handle (SHC) for removing undesired electrolytic capacitor. Consequently, becomes multi-converter system. In this paper, stage or in system is categorized into two types terms of control objectives, i.e., bus-volt...
In electrolytic capacitorless permanent magnet synchronous motor (PMSM) drives, the DC-link voltage will fluctuate in a wide range due to use of slim film capacitor. When flux-weakening current is lower than $-\psi_{\mathrm{f}}/L_{\mathrm{d}}$ during high speed operation, control loop transform ...
Sharp LC resonance peak may enlarge inherent harmonics, dominant harmonics of the supply voltage generated by a three-phase diode rectifier, around frequency, which will intensify fluctuations dc-link voltage, and grid currents in motor drives with small capacitor. In this article, novel suppre...
Nowadays, the doubly-fed induction generators (DFIGs) based wind turbines (WTs) are the dominant type of WTs connected to grid. Traditionally the back-to-back converters are used to control the DFIGs. In this paper, an Indirect Matrix Converter (IMC) is proposed to control the generator. Compared with back-to-back converters, IMCs have numerous advantages such as: higher level of robustness, re...
