Abstract—
A single-phase induction motor using a new electronically controlled capacitor is described. The system uses a dc capacitor switched by a transistor H bridge. By proper control of the transistor switching, the circuit synthesizes a continuously variable capacitance in series with the auxiliary winding. The system could be used to replace standard single-phase motor capacitor configurations to provide improved ma¬chine performance. Basic system operation, a comparison with conven¬tional motor operation, and illustrations o ....etc

Electric Double Layer Capacitors (EDLC)


INTRODUCTION
Electric Double Layer Capacitors (EDLC) are also called super capacitors or ultra capacitors. They store energy in the form of static charges. EDLC resembles the ordinary capacitors but having high energy density. EDLC have very low working voltage ,and are used in hybrid vehicles. EDLC Ëœs are rated from Farads to Kilo Farad ranges
HISTORY & PRESENT
Electric double layer effect was first noticed by General Electric engineers in 1957. B ....etc

Abstract:
This paper deals with the direct torque control of capacitor multilevel VSI actuators. The active control strategy high voltage I high power induction motors fed by floating egy for well-balancing the capacitor voltages is presented highlighting an optimal pattern. The efficiency of this approach is compared to the well-known passive method and it is illustrated by simulation. In the next section, a controlled cycle based algorithm is proposed as an attractive solution for a high performance torque control ....etc

Electronic starter for single phase induction motors
with starting capacitor or double capacitor



Description

To generate a rotating field to start the single phase
induction motors type EAS and EDS from EMG, an
auxiliary winding with start capacitor is used. This causes
a higher starting torque for these types of motors. After
the start of the motor the starting capacitor is cut off.
Due to the motor type, the auxiliary winding may be
energized by a running capacitor in steady-state (type
EDS).

Abstract “
Solid state control of ac power using diodes, thyristors and triacs injects the harmonics into the ac mains. These injected harmonics cause low efficiency in the supply system, poor power factor and EMI problems. Active filters have been considered a potential candidate to reduce these problems. This paper deals with an active power-filter (APF) based on simple control with optimum selection of energy storage capacitor. A voltage source inverter with hysteresis current control is employed to form the APF, which uses minimum ....etc
