Alexander B. Nassif and Jing Yong [7] have proposed a method to identify the consumers generating inter harmonic frequencies. The inter-harmonics can be measured by means of Impedance based approach applied at the metering point. The main idea is that, the inter-harmonic impedance of the system is much smaller than that of an inter-harmonic generating load. This method can identify the source of each inter-harmonic component without having to rely solely on the active power measurement and requires

ideology of electronics and this ignited my curiosity further. Background While I pursued the curriculum in Electronics engineering, I got abundant exposure to the different genres in electronic equipment’s such Semiconductors, Amplifiers, and Capacitors. The nature of the undertaken project was to design a Boost converter and was carried out in

circuit. RC circuits contain resistors and capacitors, and are connected to a voltage source. In our case, this voltage source was the battery. When we were measuring the voltage on the computer, we used a switch instead of manually connecting it, so that it would be a smoother action. When the switch is up, it is disconnected from the circuit, and when the switch is down, it is connected to the circuit. When the voltage source in a RC circuit charges a capacitor, it will produce a time- varying current

In variable gap capacitor distance between plates is a variable where as overlap area of capacitor plate is constant. Lets place two plates of capacitor in such a way that one plate is fixed and other is free to move in y-axis. Also voltage applied is V and overlapping area of capacitor is z0 x0. Then the force acting upon the plate is given by F=-1/2 (ϵ0〖 z〗_0 〖 x〗_0)/(y+y_0 )^2 V^2 {Insert diagram}

Power electronics circuits convert electric power from one form to other using electronic devices. By using semiconductor devices as switches power electronics circuits function, thereby controlling or modifying a voltage or current.Power electronics application range from high-power conversion equipment such as dc power transmission to everyday appliances, such as cell phone chargers, cordless screwdrivers, power supplies for computers, and hybrid automobiles. Power electronics includes applications

In a research article [9], the frequency response characteristics of the system can be altered when the harmonic distortion levels are not within the acceptable limits through changing sizes or locations of the capacitor, by changing source characteristics, or by design a harmonic filter. Filters are the most common solution as it can provide reactive power support at the fundamental frequency and a low impedance path for one or more harmonic current components to flow. The filter elements must

A small bundle of specialized cells located in the right atrium of the heart called the Sinus node is where the impulse of the heart starts. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles which sets the rate and rhythm of the heartbeat. A pacemaker is needed to maintain an adequate heart rate, either because the heart’s natural pacemaker – sinus node – is not fast enough or there is a block in the heart’s conduction

Electric power converters For various purposes electric power or electric energy is converted from one form to another, such as converting from AC to DC, or vice versa or just changing the voltage or frequency level. According to the input and output are alternating current (AC) or direct current (DC), power conversion can be classify as: AC to DC Rectifier Mains power supply unit (PSU) Switched mode power supply DC to AC Inverter DC to DC DC-to-DC converter Voltage stabilizer Linear regulator

Moreover, input node voltages and currents can be referred to the input terminal voltages of the inverter with reference to ground point and the corresponding currents from each node of the capacitors to the inverter respectively. As an example, input node (dc) currents by I_1,I_2 etc., and input node (dc) voltages are designed by V_1,V_2, etc as shown in Figure 1a. V_a,V_b and V_c are the root mean square (rms) values of line load voltages;

the implementation of the filter results in cost savings, reduction in overall weight and size of the components. Good performance can be achieved in the range of power levels up to hundreds of kW, with the use of small values of inductors and capacitors. The higher harmonic attenuation of the LCL filter allows the usage of lower switching frequencies to meet harmonic constraints Figure 3.9: Basic block diagram showing LCL filter in a grid-connected photovoltaic system
