“…Fluorescent luminaires can be compact or fluorescent tubes; some of these can be characterized by high levels of total harmonic current distortion, which is close to 100% [25][26][27]. Fluorescent recessed lightings are frequently used in buildings, although there are only limited studies when compared to CFLs.…”

The high utilization of nonlinear devices in buildings increases harmonic distortion in the electrical voltage and current signals, which has led to the requirement of characterizing and predicting the impact of such devices on low-voltage networks using load models. One of the charges that still performs an important role in the energy consumption of commercial, industrial, and educational buildings is the recessed fluorescent light with electronic ballast, which is commonly used in Colombia. However, information regarding the modeling of their behavior in the case of distorted power supply voltages is scarce. Therefore, this work presents the parameter configuration and performance analysis of two load models in the time domain, i.e., ZIP and exponential, and one model in the frequency domain, i.e., Norton equivalent model to the coupled admittance matrix method, for two commonly used recessed fluorescent lights.

“…12 Beyond this range, excessive switching loss and parasitic components may cause inefficient operation of the electronic switches S 1 –S 4 . 27 The number of desired power levels ( n ) must be an integer which is utilized to formulate a vector X(j) ( j = 1,2… n ). Members of X(j) are the desired power levels (%) with equal intervals arranged in descending order in the 100%–50% dimming range.…”

This paper presents a methodology to design acoustic resonance-free, high-frequency, dimmable electronic ballasts for high-pressure sodium vapour (HPSV) lamps having a range of rated wattage (70–400 W). After estimation of the ‘quiet window’ of an HPSV lamp, the proposed iterative algorithm is able to determine the acoustic resonance-free driving frequencies of a design ballast corresponding to 50%–100% power level. On the other hand, a developed wattage and voltage independent HPSV lamp model facilitates finding the required electrical characteristics of HPSV lamps without performing laboratory experimentation. Using the estimated driving frequencies of a design ballast and the synthesized electrical characteristics of the lamp, the design circuit parameters of an electronic ballast are determined. Performance evaluation of the designed ballasts, carried out on the Matlab–Simulink platform, indicates several important attributes, viz. higher power control accuracy (deviation ≤3.69%), near-unity lamp power factor (≥0.98), lower lamp current crest factor (<1.7) and lower lamp current total harmonic distortion (≤12.63%). Results establish the effectiveness of the proposed design methodology to design lightweight and compact electronic ballasts for HPSV lamps with less effort than conventional design practice.

Integrated compact fluorescent lamps (CFLs) are gaining a major share of the market owing to their low power consumption and long life. In this work the performance of integrated electronic ballasts for both electrode and electrode-less lamps is explored in terms of their efficiencies. The power losses were measured in a high precision mini-calorimeter. A break down of the power losses in the two ballast circuits was done by simulation in PSPICE environment. Moreover, the effect of voltage dimming upon the power losses in electrode-less lamp ballast is also shown. The results are helpful in pointing to how the efficiency of these ballast circuits can be improved.
