Introduction

The S70GR Series of single-phase rectifiers is a newer type of diodes with a wide range of applications. It has become increasingly popular due to its ability to provide a higher level of current, voltage and efficiency when compared to traditional rectifiers. In this article we will discuss the application field and working principle of the S70GR series.

Application field

The S70GR series of single-phase rectifiers has a wide range of applications. It is widely used in the industries of power supplies, Switch Mode Power Supplies (SMPS), pulse power supplies, motor drives, welding machines and other electrical equipment that requires a higher level of performance for rectifier applications. The S70GR series is ideal for applications where it is important to maximize efficiency, reduce power losses and increase the life cycle of the equipment. It also provides a higher level of safety as it has an integrated thermal protection system, which ensures the rectifier will not overheat during operation.

Working principle

The S70GR series of single-phase rectifiers works by allowing current to flow through the diode in only one direction. This is due to the diode having a polarized nature, which is caused by the retarding force of the anode-cathode depletion region. When the anode voltage is higher than the cathode voltage, current will begin to flow through the diode. However, if the anode voltage is lower than the cathode voltage then no current will flow. The S70GR series of single-phase rectifiers has several advantages over other types of rectifiers. It is fast switching, allowing it to operate over a wide frequency range. It is also capable of achieving higher current and voltage limits on its output, resulting in higher efficiency and performance. To achieve maximum performance, the S70GR series is equipped with an integrated thermal protection system to ensure the rectifier does not overheat.

Conclusion

The S70GR series of single-phase rectifiers is a newer type of diode with many advantages over other types of rectifiers. It offers a higher current, voltage and efficiency when compared to traditional rectifiers and has a wide range of applications including power supplies, Switch Mode Power Supplies, motor drives, welding machines, and other electrical equipment. The integrated thermal protection system ensures the rectifier does not overheat during operation. By understanding its application field and working principle, we can better appreciate this new technology and find the best ways to utilize it in our projects.
