123 Volt AC Lamp Dimmer Full Wave SCR - (circuit / schematic design added 6/06) |
|
124 VAC Lamp Dimmer (full wave SCR) - The full wave phase control circuit below
was found in a RCA power circuits book from 1969. The load is placed in series with
the AC line and the four diodes provide a full wave rectified voltage to the anode of
a SCR. Two small....(electronic diagram added 6/06) |

Circuit offers improved active rectification - 02/06/03 EDN Design Ideas /
(added 1/05) Rectifiers convert ac signals to dc. You can combine a diode and a load
resistor to create a half-wave rectifier, provided that the amplitude of the ac source
is much larger than the forward drop of the diode (typically 0.6V). Unfortunately, you
can't use this method to rectify signals that are smaller than a diode drop.... |

Full Wave Rectifier - This is a classic circuit that can accurately convert an AC
signal to DC. At 40KHz the input signal can be as low as 0.05 volts peak to peak.

Full wave rectifier operates to 200 MHz - (07/20/95 EDN-Design Ideas / (added
10/05) The circuit in Figure 1 uses current-feedback amplifiers to implement a
wideband full-wave rectifier for applications such as a control/AGC system reference
or as an amplitude indicator. Putting the full-wave-rectifier diodes in the feedback
loop of an op amp works better than does using simple diode-based rectifiers. The op
amp's loop gain .... |

Full Wave Rectifier uses Current Feedback Amps - 03/27/97 EDN-Design Ideas /
(added 3/03) Doubling or rectifying a continuous-wave signal by using diode bridges
usually causes problems with low inputs or at high frequencies. However, with the use
of a 1.2-GHz current-feedback op amp and low-capacitance Schottky diodes in the
feedback path, the circuit in Fig 1 can double the input frequency from 100 to 200
MHz..... |
