Abstract
The thesis presents a detailed design information and
performance characteristics of a parallel ferrosesonant circuit
which can be used for A.C. Voltage stabilization.
Chapter I gives
An Introduction explaining the possibility of using the
parallel ferroresonant circuit for voltage stabilizatiop.
A detailed discussion of previous works in both the
applicatio~ and ana lysis of the serios and parallel ferroresonnnt
circuits.
The method of analysis of the parallel ferroresonant
circuit with an inductance core wh i.ch is assumed to have a single
valued magnetization characteristic which neglects the inductance
in the saturation domain.
Chapter 2 gives
Tho design and construction of the parallel ferroresonant
circuit is describeds
The experimental determination of the w ave forms of the
voltages, currents and flux densities in the cor e is determined.
Because of the distorted wave forms of the currents and
voltages in the circuit, t ho Ro!·i.oS. values of these quantities
are determined by me ans of a D.C. - A.C. thermal transfer
voltmeter l
- iii -
Complete families of curves showing the effect of variation
of circuit parameters as well as the load resistance on the output
voltage is determined experimentally. An equation which relates
the amplitude of the sinuisoidal input voltage \’/iththe parameters
of the non-linear inductance and the saturation angle of the core is
derived for both conditions of normal and over ey.citation.
Chapter 3 gives
The theoretical analysis of the parallel ferroresonant cir-
cuit. This analysis is based on a set of n~n-linear differential
equations wh Lch describe the behaviour of the circuit at any
instant. Time intervals are found within half a period of
sinuisoidal input voltage. from the wave forms of the flux denSity
of the core within any time interval the core way have one of two
conditions: saturated or unsaturated consequently the set of non-
linear equations will become linear w i.t hi.n the limits of any
interval.
Expressions for current and voltage in the circuit
and also the boundary angles between the time intervals are determined
with the aid of Laplace ~ransfmrmation for every interval.
FinallY an expression for the average value of the output
voltage in terms of the circuit para ...eters as weLl,as the
amplitude of the sinuisoi~al input voltage is derived.
A comparison between expe ri aent al, and theoretical results is
discussedo
