A rectifier is an electronic component that converts alternating current (AC) into direct current (DC). This process is essential in many medical devices and power supply systems.
Most medical equipment requires stable DC power to operate correctly. Since standard wall outlets supply AC power, rectifiers are used to convert that power into a usable form.
Devices like patient monitors, infusion pumps, and imaging systems all rely on power supplies that include rectifiers.
A rectifier uses diodes to allow current to flow in only one direction. By blocking the negative portion of an AC waveform, the rectifier produces a DC output.
In a patient monitor, incoming AC power from the wall must be converted to DC before it can power internal circuits. A rectifier performs this conversion, ensuring stable operation of sensitive electronics.
You will often see questions asking:
