Four Quadrant Operation Of DC Motor
Describe the basic SHA operation with the help of its four mode specifications. Answer : Sample-and-hold amplifier (SHA) is a unity gain amplifier with a mode control switch where the input of the amplifier is connected to a time-varying signal. A trigger pulse at the mode control switch ... but other forms, such as optical and mechanical forms, are possible. Also denoted S/H. ...
Explain two-quadrant chopper......... Answer : Two quadrant chopper: There are two semiconductor controllable switches in the two-quadrant chopper. Two quadrant type A chopper: The figure shows the type A chopper. Both the switch never turn on at ... 2 are turned on then Vo=Vs. When chopper 1 and chopper 2 are off then Vo=-Vs. ...
Explain SEPIC converters.............. Answer : SEPIC converter: SEPIC stands for single-ended primary inductor converter. SEPIC converter is a DC to DC converter, the output of SEPIC converter can be more than input voltage or less than ... . By controlling duty cycle of transistor the output of SEPIC converter can be controlled. ...
Give the operation of single phase full wave bridge controlled converter with RL load with a neat diagram. Also draw its waveform. Answer : Single phase fully control bridge converter with RL load: 1. During positive half cycle of input voltage, T1 and T2 are forward biased and during negative half cycle, T3 and T4 are forward biased. Therefore, T1-T2 ... cycle till the firing of next pair of SCRs as shown in the waveform. ...
