2. Pulsed DC - Wikipedia

   en.wikipedia.org/wiki/Pulsed_DC

   Types of electric current Rectification of a sine wave produces pulsed DC. Pulsed DC ( PDC ) or pulsating direct current is a periodic current which changes in value but never changes direction. Some authors use the term pulsed DC to describe a signal consisting of one or more rectangular ("flat-topped"), rather than sinusoidal, pulses.

3. Rotary converter - Wikipedia

   en.wikipedia.org/wiki/Rotary_converter

   1909 500 kW Westinghouse rotary converter. A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter.. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting.

4. Vibrator (electronic) - Wikipedia

   en.wikipedia.org/wiki/Vibrator_(electronic)

   A vibrator was used to provide pulsating DC which could be converted to a higher voltage with a transformer, rectified, and filtered to create higher-voltage DC. It is essentially a relay using normally closed contacts to supply power to the relay coil, thus immediately breaking the connection, only to be reconnected very quickly through the ...

5. Ripple (electrical) - Wikipedia

   en.wikipedia.org/wiki/Ripple_(electrical)

   Ripple (specifically ripple voltage) in electronics is the residual periodic variation of the DC voltage within a power supply which has been derived from an alternating current (AC) source. This ripple is due to incomplete suppression of the alternating waveform after rectification. Ripple voltage originates as the output of a rectifier or ...

6. Alternating current - Wikipedia

   en.wikipedia.org/wiki/Alternating_current

   A schematic representation of long distance electric power transmission. From left to right: G=generator, U=step-up transformer, V=voltage at beginning of transmission line, Pt=power entering transmission line, I=current in wires, R=total resistance in wires, Pw=power lost in transmission line, Pe=power reaching the end of the transmission line, D=step-down transformer, C=consumers.

7. Pulse generator - Wikipedia

   en.wikipedia.org/wiki/Pulse_generator

   Pulse generators are generally voltage sources, with true current pulse generators being available only from a few suppliers. Pulse generators may use digital techniques, analog techniques, or a combination of both techniques to form the output pulses. For example, the pulse repetition rate and duration may be digitally controlled but the pulse ...
