  • Using synchrotron X-ray diffraction the thermal behaviour was studied of the cubic phases in the 1-monooleoyl-rac-glycerol (MO)/n-octyl-b-D-glucopyranoside (OG)/ 2 H2O system with 58 or 45 wt % MO concentration and varying OG/ 2 H2O contents. These MO contents correspond to a Pn3mcubic single-phase or aPn3mcubic phase in excess water on the binary MO/water axis of the ternary phase diagram. The cubic liquid crystalline phases are stable with small fractions of OG, while higher OG concentrations trigger a cubic-to-lamellar phase transition. ...

  • The phase locked loop is a feedback system comprised of a phase comparator, a low pass filter and error amplifier in the forward signal path and a voltage-controlled oscillator (VC0) in the feedback path. The block diagram of a basic PLL system is shown. Perhaps the single most important point to realize when designing with the PLL is that it is a feedback system and, hence, is characterized mathematically by the same questions that apply to other, more conventional feedback systems.

  • Author: Rakesh Parekh Microchip Technology Inc. created naturally in the stator because of the nature of the supply. DC motors depend either on mechanical or electronic commutation to create rotating magnetic fields. A single-phase AC induction motor depends on extra electrical components to produce this rotating magnetic field. Two sets of electromagnets are formed inside any motor. In an AC induction motor, one set of electromagnets is formed in the stator because of the AC supply connected to the stator windings.

  • Uncontrolled Single-Phase Rectifiers Sam Guccione Single-Phase Half-Wave Rectifiers Operation A single-phase half-wave rectifier consists of a single diode connected as shown in Fig. 4.1. This is the simplest of the rectifier circuits. It produces an output waveform that is half of the incoming AC voltage waveform. The positive pulse output waveform shown in Fig. 4.1 occurs because of the forward-bias condition of the diode. A diode

  • If each voltage is connected to a circuit with the same power factor and the three currents return along the same conductor, then the vector sum of the three return currents is zero. Thus instead of three full sized return cables, only one of smaller size is needed. If none of the load is single phase, then the neutral is not needed at all. High voltage supplies are nearly always three phase without a neutral conductor. There is a great economy in distribution costs if the electricity can be supplied in three phases. ...

  • The origin of the electrolytic capacitor or condenser can be traced to the second half of the 19th century when the discovery was made (Wheatstone, Buff, Ducretet) that a film can be formed on aluminum electrochemically and that it will exhibit unidirectional electrical conductance and other peculiar properties. One of the early attempted applications of the electrolytic capacitor was in conjunction with the starting of single-phase induction motors; efforts were also made to utilize it for power factor correction in alternating current circuits.
