Abstrud This paper presents a dynamic model for HID lamps; the model is based on thermal and electric principles, and it includes the plasma characteristics. Also, the model considers that the conductivity of the plasma inside the lamp depends of the heat flow from the inside of the lamp to outside. The heat flow of the lamp has an analogy with electrical(More)
This paper deals with electrical modeling of glow dielectric barrier discharge taking into account the waveform slope as the main parameter. Two equivalent electrical models of dielectric barrier discharge are commented. An equivalent electric model is proposed for this kind of discharge fitted using short-pulsed excitation. This model can be used as an(More)
In this paper, the use of input current shaper converters (ICSCs) working in discontinuous-conduction mode to stabilize the discharge arc in high intensity discharge lamps without close loop control is proposed. The analysis of how the ICSC stabilizes the lamp current, the description of the proposed topology and the design methodology are presented.(More)
Due to recent tendencies to optimize the use of the discharge lamps and the pollution problem caused by mercury, this paper outlines a simple approach that puts the reuse of tubular fluorescent lamps into perspective. The operation of the lamp is through dielectric barrier discharge which is powered using short pulses voltage. A Class-E converter, which is(More)

Due to recent tendencies to eliminate the electrodes in discharge lamps, this paper presents a feasibility study to determine whether is possible to replace electrode terminals with capacitance coupling (dielectric barrier discharge) operating as glow discharge. The results showed that is possible to operate a fluorescent lamp using dielectric barrier(More)

The commutation frequency in a sliding mode control (SMC) for DC-DC converter is affected by main voltage and load variations. This problem is undesirable for L and C component design. To maintain a constant-switching frequency under variations in load and main voltage, a constant-frequency limiter based on microcontroller is proposed. This limiter is very(More)

In this paper a stability analysis based on the remaining dynamics for an HID lamp and electronic ballast without resonant tank (non resonant ballast) is presented. This analysis uses the non linear lamp model. The lamp is the metal-halogen lamp (CDM-TD70/830). The system model is based on Euler-Lagrange modeling and the average modeling technique. The(More)
