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.

Ideal Blocking Diode Circuit for
Photovoltaic Solar Panels
Most photovoltaic solar panels are used to charge a battery during the daytime.
Nearly all panels come equipped with a blocking diode. The diode prevents DC
current from flowing backwards from the battery bank into the panel at night.
The usual blocking device of choice is a schottky diode with a typical 0.5v voltage
drop. In some large panels, which can often source over 4 amps of current, the
power loses due to this voltage drop can add up. As an example a 4KW solar
power system ....

|
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

2 op amps provide averaged absolute value - 30-Oct-03 Issue of EDN
The circuit in Figure 1 is useful when you need amplitude demodulation or an
averaged absolute-value conversion. The circuit comprises two stages, the first
of which, IC1A, is a differential-output absolute-value converter. The second
stage, IC1B, is a traditional differential amplifier. The combination of the two
stages performs single-ended absolute-value conversion but only if R3>>R2....

Circuit Forms Ideal Diode Function - This circuit uses a low power op amp and a
p-channel FET to form a diode function with a very low 0.05 volt voltage drop. With
the selected FET, the circuit can handle up to 2 amps of current. Higher currents
are possible with a FET with a lower channel resistance. The total current drawn by the
circuit during operation is a low 20 microamps. The maximum voltage is 15v.

Circuit offers improved active rectification - 6-Feb-03 Issue of EDN
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.... [Design Idea by Reza Moghimi,

Full wave rectifier operates to 200 MHz - 07/20/95 EDN-Design Ideas....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.... EDN is

Full Wave Rectifier uses Current Feedback Amps - 03/27/97 EDN-Design
Ideas.... 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.... EDN is migrating

high-speed, full-wave rectifier-or absolute-value circuit-that uses a high-speed clamping
amplifier, IC2. This circuit is faster and performs better than rectifiers employing
diodes in their amplifiers' feedback paths. These diode-based circuits have limitations at
lower signal-input levels and higher bandwidths. These limitations.... EDN is migrating
