The traditional method of the sinusoidal current synthesis (SCS) would deteriorate the distortion level in the common coupling, thus result in the harmonic propagation through the power distribution system. The method of the resistive load synthesis (RLS) can compensate the mains current in phase with the mains voltage in spit of the mains voltage distort or not. The character of the system is a resistive load. The adaptive inverse control is a novel intelligent control method. The adaptive inverse control is used to control the APF to synthesis the resistive load. The whole power distribution system is regarded as a generalized active power filter. The inverse of the plant model is obtained by using an off-line identification technique. The inverse of the model is used to be the controller to control the action of the active power filter so that the output of the voltage of the dc capacitor to follow the reference input. The action of the active power filter makes the system to synthesize a resistive load. The harmonic propagation can be damped out and the harmonics and reactive power can be compensated. The power factor can be corrected to unity.

Many techniques exist that allow an insulated transmission of the driving signal. Some, like the level-shifter or the optocoupler are commonly used in medium voltage range but are totally unsuited to high voltage. In this last case, a classical solution leads to use, for each IGBT, a DC supply with a high insulation transformer for energy transmission and an optic fiber for the transmission of information. This solution is reliable, fast, and not sensitive to disturbances. However, in the case of numerous switches to drive, this solution becomes costly and bulky. Thus, in this paper, we propose a driving system well suited to high voltage, which can be insensitive to high-level disturbances. A wireless solution coupled to an energy supply loop is proposed, in order to reduce the cost and bulkiness of high power converters. The advantage of this solution lies in a very low propagation time, a strong immunity to noise if signal coding is well studied and a simplified supply system to drivers","PeriodicalId":448315,"journal":{"name":"2006 CES/IEEE 5th International Power Electronics and Motion Control Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128207918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electronic ballast with constant-frequency control, in which the DC-bus voltage is fed by a power-factor corrector, has a low-frequency ripple, which can cause lighting flickers in fluorescent lamps. Precise image-detecting systems require lighting sources (such as fluorescent lamps) with low levels of lighting flicker. The presented ballast operates by detecting the DC-bus voltage ripple as a feed-forward signal in order to modulate the switching frequency of the inverter. Thus, the voltage gain of the resonant tank is adjustable. As a result, the lighting flicker caused by the DC-bus voltage ripple can be decreased.

Actually, while returning reactive power to power supply but suffering a positive measure, average power factor is lower than the primary one, thus, penalty is inflicted for poor power factor. To rescue the situation, in the paper we propose a novel capacitor switching strategy based on rough functions concept. The method firstly applies artificial neural networks to on-line monitor reactive current in traction load arms, then according to rough function, yields the discrete series space of reactive current for the intensity and speed of capacitor grouping switching, and generates decision-making rules for capacitor grouping switching. Meanwhile, considering the existence of three-time harmonics in traction loads, filter is designed in each grouping capacitor to filter a part of harmonics. The investigation indicates that the proposed method can overcome the deficiencies of traditional methods and duly trace dynamic change of loads, and power factor is also dramatically improved.
