AC DC converters are electronic devices which are used to convert alternating current (AC) electricity to direct current (DC) electricity. They can be used to convert AC power to DC power, or directly convert AC power to an electrical energy output in the form of DC power. AC DC converters are commonly used in applications such as: charging a sealed lead acid battery, powering DC equipment such as medical devices, providing power to portable electronics, providing power to LED lighting systems, converting computer-controlled AC signals to DC signals, and many more.

The 2909575 application field and working principle of an AC DC converter can best be explained in terms of a device known as a chopper. A chopper is a device used to vary the frequency and voltage of an AC wave form to produce desired DC power levels. It consists of a switch, which is used to control the power flow through the converter, and an inductor, which serves to store energy and acts as a filter for the power being supplied to the device. When the switch is closed, the AC waveform is cut off, thus allowing energy to be transferred into a DC waveform. When this happens, a steady voltage will be applied to the connected device, and a constant current will flow through it.

In the AC DC converter, the inductor acts as a filter, filtering the high frequency voltage peaks, thus providing a steady DC voltage level. The chopper uses the inductor to control the power flow to the device, and the energy level and speed of the DC signal can be adjusted by varying the duty cycle of the chopper. This allows for a greater level of control over the power flowing to the device. The current control of the chopper is also used to regulate the current flowing to the device, and in some cases, AC DC converters may also contain additional components such as capacitors, resistors, and amplifiers, to help regulate the current flow.

AC DC converters can be used in a wide variety of applications ranging from supplying power to portable electronics, providing power to LED lighting systems, controlling the speed of motors, and producing DC signals from AC signals for computer-controlled operations. AC DC Converters are also used in more advanced applications such as controlling and regulating the power supply to renewable energy sources such as solar panels. Overall, AC DC converters are a versatile tool for a variety of applications, and their ability to handle a wide range of input voltages makes them highly useful in many applications.
