Introduction of Fast Recovery Diode in Linear Power Supplies

Linear power supply is a commonly used power supply in electronic equipment. It provides a stable power supply by adjusting the linear relationship between voltage and current. А fast Recovery Diode (ФРД) is crucial in many linear power supplies. A speedy recovery diode is a semiconductor device with quick recovery characteristics. It can effectively suppress reverse current during the power conversion process, thereby protecting the power circuit.
