Information about Power Rectifiers

Power rectifiers are electrical devices that convert alternating current (AC) to direct current (DC). They are an integral part of telecom rectifiers for the telecommunications industry, and in battery chargers, DC power systems, and other power system devices. Power rectifiers include one or more diodes, electronic components that conduct current in only one direction. Single-diode power rectifiers omit the negative portion of the AC waveform. By contrast, multi-diode power rectifiers reverse the negative portion of the AC waveform, allowing it to merge with the positive part to produce an entirely positive current. Typically, single-phase power rectifiers use four diodes. If the AC is center-tapped, then the diodes are arranged anode-to-anode or cathode-to-cathode to form a full-wave rectifier. If the AC is not center-tapped, then the four diodes are arranged in a bridge. With three-phase AC power, six diodes are used. Each of the three pairs is arranged in series. Many diodes have four terminals so that they can be used in a single-phase split supply, a half-bridge, or for three-phase use.

Products & Services Related to Power Rectifiers

AC Power Sources

AC power sources provide alternating power and typically have adjustable output values for the testing of component response at various voltage, current and frequency levels.

AC-DC Adapters

AC-DC adapters accept AC input voltage directly from a wall outlet, and output DC voltage.

Current Sources

Current sources provide reliable current for electrical component testing and for powering specialized components.

DC Power Systems

DC power systems provide continuous DC power through multiple outputs. Most DC power systems include a battery backup, temperature compensation, and other features.

High Voltage Power Supplies

High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts.

Medical Power Supplies

Medical power supplies produce conditioned outputs for medical devices, instruments, and equipment.

Programmable Power Supplies

Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency. They include a processor, voltage/current programming circuits, current shunt, and voltage/current read-back circuits.
