Solenoids are commonly used in fuel injection systems, in process automation, medical systems, etc. They have numerous advantages: they are fast, reliable, compact and produce a high force output, making them a competitive replacement option for purely mechanical actuators and pneumatic control valves. However, their coil inductance and electromagnetic force vary non-linearly as a function of position...
This paper focuses on modeling and performance predetermination of a photovoltaic (PV) system with a boost converter fed permanent magnet direct current (PMDC) motor-centrifugal pump load, taking the converter losses into account. Sizing is done based on the maximum power generated by the PV array at the average irradiation. Hence optimum sizing of the PV array for the given irradiation at the geographical...
Dynamic Voltage Restorers (DVR) are commonly used in the distribution network to protect voltage sensitive loads from the effects of voltage sags, swells and imbalances. This paper presents the modelling and control principle of a battery based DVR. The energy storage element is used to absorb and inject active power during steady-state operation. Finite Impulse Response(FIR) filter based PLL is used...
PV modules are increasingly used in battery charging applications in home inverter systems due to the power crisis faced in developing countries. This work aims at maximizing the use of solar energy by charging the battery as well as by supplying it to the loads when in excess. This system is implemented using two subsystems namely a charge controller and a Power Flow Management System(PMS). The charge...
