Journal of International Council on Electrical Engineering Vol. 1‚ No. 1‚ pp. 7~13‚ 2011 7 Single-tuned Passive Harmonic Filter Design Considering Variances of Tuning and Quality Factor Young-Sik Cho* and Hanju Cha† Abstract - This paper presents how to select tuning factor and quality factor in designing of a single-tuned passive harmonic filter. Tuning factor and quality factor must be considered before a decision of filter parameters(R‚ L and C). In literature‚ the study about these

These days‚ in many homes‚ it is virtually impossible to have a so called modern kitchen‚ without having a microwave oven in it. The microwave oven could probably occupy the second place (after the refrigerator)‚ in terms of dependence‚ in the kitchen. This magical piece of technology has revolutionized the way people‚ and the food industries cook food. The microwave oven is only a natural evolution of technology; to fit into this fast-paced world. As in every evolutionary process‚ one must look

Nebulizer A nebulizer is a device that is used for breathing treatments such as asthma‚ cystic fibrosis‚ and other respiratory illnesses. It changes liquid medicine into an aerosol. Aerosol is a "mixture of gas and liquid particles‚" and the best example of a naturally occurring aerosol is mist‚ formed when small vaporized water particles mixed with hot ambient air are cooled down and condense into a fine cloud of visible airborne water droplets. Introduction As

Research about LM317 Positive Adjustable Linear Voltage Regulator: The LM317T is a 3-terminal integrated circuit which can supply a load current of up to 1.5 Amps with an output voltage of between 1.2V and 37 Volts. It accepts an input voltage of between 3 and 40 volts. It can be used to regulate either current or voltage in situations where a fixed current or fixed voltage is required. The level of current or voltage required can be adjusted by connecting the chip in series with a fixed resistor

the energy stored in the leakage inductance and absorbs the voltage spikes on the main switch voltage. The series configuration with a voltage doubler at the second side contributes to a high-voltage gain and reduces the voltage stress across the rectifier devices. The output diode reverse-recovery problem is naturally mitigated by the leakage inductance of the coupled inductors. Moreover‚ the active control with a neutral-point potential balance and a phase-deficient operation of the proposed converter

Alternating current bridges….it’s applications and various perspectives revealed….. ALTERNATING CURRENT BRIDGES:- INTRODUCTION:- A bridge circuit is a type of electrical circuit in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging points is often adjustable when
