A  rectifier  is an electrical device that converts alternating current (AC) to direct current (DC), a process known as  rectification . Rectifiers have many uses including as components of power supplies and asdetectors of radio signals. Rectifiers may be made of solid state diodes, vacuum tube diodes, mercury arc valves, and other components and then we have to add those things. A device which performs the opposite function (converting DC to AC) is known as an inverter. When only one diode is used to rectify AC (by blocking the negative or positive portion of the waveform), the difference between the term  diode  and the term  rectifier  is merely one of usage, i.e., the term  rectifier describes a  diode  that is being used to convert AC to DC. Almost all rectifiers comprise a number of diodes in a specific arrangement for more efficiently converting AC to...

The following couple of circuit diagrams provide a glimpse of the configuration for making a precision rectifier and direct coupled power source circuits.  Precission Rectifier circuit diagram. Direct Coupled Power Circuit Diagram CMOS Power Booster Circuit Diagram The MC1556 operational amplifier way be used as a voltage follower ln a hid; amplifier application. The high input impedance avoids loading effects on the bridge and transforms the impedance down to a level where a third amplifier used in a differential mode can provide voltage gain, ll) in this case. The third amplifier employs the standard offset adjust circuit to provide nulling capability for the configuration. Although the circuit is shown for complementary supply voltages, , it lends itself well to operation from a single supply since the bridge can be operated iust as well from the single supply. One must, however,,provide for biasing the nowgrounded 100 kS2 resistor to half the supply voltage using a simple resis...
