This paper deals with the elimination of harmonics at PCC in the presence of non-linear type of loads. Introduction of five-level DSTATCOM at PCC injects compensating currents for the minimization of harmonic content in the source currents. Non-linear loads when connected to the system draw non-linear components of current leaving undesired harmonics at the source side. DSTATCOM when connected ...

This paper presents a fuzzy logic, PI, average current controlled shunt active power filter used to compensate for harmonic distortion in three-phase four-wire systems. The shunt active filter employs a simple method for the calculation of the reference compensation current based on Fast Fourier Transform. The presented Shunt Active Power filter is able to operate in balanced, unbalanced and Va...

In this paper, it is first attempted to provide a small signal model of the photovoltaic (PV) system, DC-DC boost converter, and pulse width modulation (PWM) generator. Then, technique provided for maximum power point tracking (MPPT) in grid-connected solar systems based on variable adaptive perturbation observation with predictive control PV current. An innovative aspect proposed current metho...

Gliomas are primary brain tumors associated with a poor prognosis partly due to resistance to conventional therapies. To overcome this problem, we investigated the combined effects of gamma knife radiosurgery (GKS) and an antiangiogenic agent, thalidomide (THD), or a chemotherapeutic agent, temozolomide (TMZ), on a rat glioma model. GKS (20 Gy single dose) alone and/or drugs (for 3 days) were d...

A novel current injection network for low-harmonic rectifiers that apply the third harmonic current injection is proposed in this letter. The current injection network requires one inductor, two capacitors, and one 1 : 1 transformer with voltampere rating of only 0.16% of the input power. The transformer is introduced to provide complete rejection of harmonic components of the injected currents...

BACKGROUND Transanal hemorrhoidal dearterialization (THD), a new approach for patients who would otherwise require an operative hemorrhoidectomy, accomplishes hemorrhoidal symptom relief with far less postoperative pain than an operative hemorrhoidectomy. METHODS THD, an ambulatory procedure, employs a specially designed proctoscope coupled with a Doppler transducer to allow identification an...

CONTEXT Hop tests are functional tests that reportedly require strength, power, and postural stability to perform. The extent to which a triple-hop distance (THD) test measures each of these characteristics is relatively unknown. OBJECTIVE To determine the extent to which the THD predicts performance on clinical measures of power, strength, and balance in athletic individuals. DESIGN Within...

The thyroid hormone (TH) system is involved in several important physiological processes, including regulation of energy metabolism, growth and differentiation, development and maintenance of brain function, thermo-regulation, osmo-regulation, and axis of regulation of other endocrine systems, sexual behaviour and fertility and cardiovascular function. Therefore, concern about TH disruption (TH...

Multilevel inverter becomes popular because of its high power, high voltage application. However it has some disadvantages such as increased number of components, complex control method and voltage balancing problems. In this paper, we proposed a new topology having level modules and H-bridge inverter, and reverse voltage technique is adopted for load. APOD based PWM technique is used to genera...
