WebI acknowledge the various textbooks/websites/publications that have helped me in preparing this video. WebMar 15, 2024 · DMAIC is a data-driven problem-solving technique designed to identify and address inefficiencies in a process, which improves its outcomes and makes these improvements more predictable. The acronym stands for the five phases — Define, Measure, Analyze, Improve, and Control, and it is pronounced “duh-may-ik.”.

WebThus, power &amp; voltage can be controlled by firing angle. Single Phase Half Wave Controlled Rectifier with 'RL' load: Figure above shows the single phase half wave rectifier with RL Load. Normally motors are inductive loads; L= armature of field coil inductance. R= Resistance of coil. In positive half cycle, SCR starts conduction at firing angle ... WebThe phase locked loop or PLL is an electronic circuit with a voltage controlled oscillator, whose output frequency is continuously adjusted according to the input signal’s frequency. A Phase locked loop is used for tracking phase and frequency of the input signal. It is a very useful device for synchronous communication.

WebFeb 14, 2024 · The principle of ON-OFF control: The on-off control is also called an integral cycle control. The on-off control is shown in the figure for single phase full wave AC voltage controller. To avoid the fluctuations at the output the turning on and off operation should be fast. The power semiconductor switches are used in integral cycle control. WebFigure 11.44 shows the schematic representation of Phase Control of Three Phase Induction Motor. Two thyristors are connected in antiparallel in each line. The firing sequence of the thyristors for all modes of operation is 1, 3′, 2, 1′, 3 and 2′ as shown in Fig. 11.45.
