YFW Diodes in Power Supply Application

1.1 Switching Power Supplies

In switching power supplies, which are widely used in electronic devices like computers, mobile phone chargers, and LED lighting drivers, rectifier diodes from YFW play a crucial role. For example, the common rectifier diodes are used to convert alternating current (AC) to direct current (DC). YFW's rectifier diodes, with their low forward voltage drop and high current - carrying capacity, can efficiently rectify the input AC voltage. This not only improves the power conversion efficiency of the switching power supply but also reduces power consumption. In a mobile phone charger with a power output of 10W - 20W, YFW's SMD - packaged rectifierdiodes can handle the required current smoothly, ensuring stable DC output for charging the phone battery.

1.2 Linear Power Supplies

Although linear power supplies are less common in high - power applications due to their relatively low efficiency, they are still used in some precision electronic equipment where stable voltage output is crucial, such as in laboratory power supplies. YFW's power zener diodes are often used in the voltage regulation circuit of linear power supplies. These zener diodes can maintain a stable output voltage even when the input voltage or load current changes within a certain range. For instance, in a laboratory power supply with an output voltage of 5V, a YFW zener diode can ensure that the voltage fluctuation is within a very small range, providing accurate and stable power for experimental equipment.
