Since the flux is sinusoidal‚ r.m.s = (form factor*average e.m.f )/turns But form factor = (r.m.s value)/(average value) =1.11‚ Then r.m.s value of E.m.f = 1.11*4F*max.Flux = 4.44F*max.Flux‚ But max .flux = B_m*A r.m.s value of E.m .f in primary turn (Tp) = 4.44F*B_m*A*T_p NOTE: Bm is assumed to be 15000Wb/m. F = Frequency of A.C input/ Output F=50 Hz By introducing stacking factor (10-8) and Tp factor (0.9) then we have Number of turns per volt = N_T/V =7/A =7/3.75=1.87turns/volts

2.2 Peltier Thermoelectric cooler (TEC) Peltier thermoelectric heat pump is a popular thermoelectric energy conversion module that applies the Peltier effect‚ transferring heat energy from one side of the device to the other side. Peltier effect occurs when two different semiconductor materials (n-type and p-type) are joined together with electric current passing through its junction. Therefore‚ the junction could either be cooled or heated [28]. The Peltier TEC device can behave like a temperature

INTRODUCTION Electronics without silicon is unbelievable‚ but it will come true with the evolution of Diamond or Carbon chip. Now a day we are using silicon for the manufacturing of Electronic Chip’s. It has many disadvantages when it is used in power electronic applications‚ such as bulk in size‚ slow operating speed etc. Carbon‚ Silicon and Germanium are belonging to the same group in the periodic table. They have four valance electrons in their outer shell. Pure Silicon and Germanium are semiconductors

INTRODUCTION 1.1 Background and Objectives 1.1.1. Background In developing countries like ours Grid power is either inadequate or unavailable in the remote and inac move the need for long and inefficient transmission lines. If a suitable water source is available nearby‚ Micro-hydro is one of the reasonable and cost effective energy technologies to be considered for rural electrification. Hydroelectric systems having capacity of 100kW or smaller are considered as Micro-hydro power. It allows
