This paper, electronic resonant ballast for a small photovoltaic powered street lighting system in remote rural area was proposed. The street lighting system was designed for rural area where the electrical transmission line cannot be commonly serviced and it is the cascade systems of the solar arrays, switching battery charger, and electronics ballast with small fluorescent lamp. The ballast i...

This paper proposes a fully analytical loss model to reduce circling currents and improve the power efficiency of class Φ2 inverter. Firstly, expression switching node voltage is derived by analyzing its harmonic components. Based on result, switch modeled as source, where circuit simplified linear network expressions branch are solved. Secondly, root mean square (RMS) values component losses c...

SLIDING-MODE control is a control technique used widely in electromechanical systems today [1–4]. It bases on using main characteristics of modern inverter semiconductor switches as Insulated Gate-Commutated Transistors (IGCTs) or Insulated-Gate Bipolar Transistors (IGBTs) that are operating in switch mode with distinctly higher switching frequency [5] than formerly used Gate-Turn-Off Thyristor...

A run-time reconfiguable array of multipliers architecture is introduced. The novel multiplier can be easily reconfigured to trade bitwidth for array size, thus maximizing the utilization of available hardware, multiply signed or unsigned data, and uses part of its structure when needed. The proposed reconfigurable circuit consists of an array of m×m multipliers, a few arrays of adders each add...

This paper presents a comparative study of two distinct modulation strategies applied to a permanent magnet synchronous motor drive, under inverter faulty operating conditions. A rotor field oriented control is used and a performance evaluation is conducted by comparing a hysteresis current control with a space vector modulation technique. Three different operating conditions are considered: no...

This paper presents a hybrid modulation technique consisting of singe-reference six-pulsemodulation (SRSPM) for front-end dc/dc converter and 33% modulation for three-phase inverter. Employing proposed novel SRSPM to control front-end dc/dc converter, high frequency (HF) pulsating dc voltage waveform is produced, which is equivalent to six-pulse output at 6× line frequency (rectified 6-pulse ou...

Recent advances in the power system handling capabilities of static switches have made the use of the voltage source inverter (VSI) feasible at both transmission and distribution levels.

-This paper describes a newly developed triggering circuit, has been use to turn on and off the solidstate switches, such as TRIAC switched capacitors applications. A linear ramp signal based synchronization technique has been propose and implemented successfully, for the capacitor switching operation of a simple power system. This scheme enables the firing circuit to adjust itself against any ...

This paper deals with a reduced switch multi-level inverter for the solar photovoltaic system-based 127-level inverter. The proposed technique uses minimum number of switches to achieve maximum steps in staircase AC output voltage when compared flying capacitor inverter, cascaded type multilevel and diode clamped use decreases cost system.
