Synchronous Vibrator and Synchronous Chopper

Synchronous Vibrator and Synchronous Chopper: Low dc current may be transformed into a high voltage dc by simple chopper action. Although an inductive type transformation process is required, the out­put dc may be obtained without rectifying devices. Figure 14.39 shows a circuit function of a synchronous vibrator. Contacts a and b connect the input dc …

Self Oscillating Converter (Transistorized Chopper Circuit)

Self Oscillating Converter (Transistorized Chopper Circuit): Self Oscillating Converter (Transistorized Chopper Circuit) – A Transistorized dc to ac converter suitable for low level dc signal is illustrated in Fig. 14.30. The unique property of this assembly is that it starts to oscillate vigorously at very low levels of dc collector voltages at only a few …

What is Electromechanical Chopper?

Electromechanical Chopper

What is Electromechanical Chopper?: Electromechanical Chopper – An ac amplifier must see ac in order to perform useful work. A fair number of chopping and modulation techniques are available to change direct current, or to change very slowly varying signals into square waves (or pulses). Associated circuitry, inserted at the amplification system common output, may …
