<p>This paper explained details of Comparison of solar based closed loop DC -DC converter using PID and ANN Control for Shunt motor drive. Solar panel output is given to full bridge converter, stepup transformer, full wave converter, ∏ filter and Shunt motor drive are connected.Comparator compare the set value and the output signal of the motor produce a signal, based on the signal, full wave conveter produce the voltage to run the motor, Speed of motor,Torque and Armature current,Rise time,Peak time, Settling time and Steady state error are measured and evaluated by experimental.A circuit operation and simulation designed for a 1000 RPM speed of shunt motor arrived and tested.</p>

Analysis of Controlled Single-phase Full-Wave Rectifier with RL Load

Diodes are popularly used in rectifiers, which convert an ac signal into a unidirectional signal. They produce a fixed output voltage only. However, controlled switches such as thyristors are used to vary the output voltage of a converter by adjusting the delay or firing angle α of the thyristors. Phase-controlled converters are simple, efficient and less expensive. There are both single-phase and three-phase converters depending on the input supply. We also have half-wave and full-wave converters. The half-wave converter has only one polarity of output voltage and current, while for the full converter, the polarity of the output voltage can be either positive or negative. The purpose of this paper is to investigate the operation of the Single-phase full-wave rectifier. Load current for the controlled full-wave rectifier with R-L load can be either discontinuous or continuous. The paper shows how the rectifier transits from discontinuous current operation to continuous current operation.

THE POINT SPREAD FUNCTION OF A FOUR-WAVE CONVERTER IN A RESONANT MEDIUM WITH ALLOWANCE FOR PUMP WAVE DIVERGENCE

An expression for point spread function has been obtained for a four-waveconverter in resonant medium modelled by four-level energy scheme. The dependences of point spread function width from pumping wave intensity and resonantmedium parameters have been found.
