Introduction

The VS-STT170M14MPBF single-phase full-wave rectifier is a three-terminal device widely used as a cost-effective, low-profile and highly efficient power supply component. It is widely used in various markets, including military, aerospace and industrial systems.

Application Field

One of the widely used application fields of this type of rectifier is in HEV and EV power charger applications, where they provide low-losses and high charging current. They are also widely used in AC-DC power supplies, where they allow excellent power conversion efficiencies and reduced electromagnetic interference. Moreover, they are widely used in battery charger applications, where they provide excellent reliability and high surge capabilities.

Working Principle

A diode bridge rectifier converts AC (Alternating Current) electric power to DC (Direct Current) electric power, with the help of four diodes, arranged as shown in the following circuit diagram. The rectifier circuit is composed of two identical bridge circuits combined together, which make it capable of rectifying AC electric current. The two bridge circuits use four diodes, two on each side of the circuit. When a single-phase AC input is applied to the circuit, the diodes conduct in a way that the voltages increase, leading to an output voltage of two times higher than the voltage at the input.

Advantages

The VS-STT170M14MPBF has a number of advantages over other rectifier solutions. First of all, it has low forward voltage drop and low reverse current, which improve converter efficiency, reduce circuit switching losses, and enable higher current density. Second, it offers high surge current withstand, which improves the power integrity of the system and increases the reliability of the device. Moreover, it has small size and low profile, allowing it to be used in space-constrained applications. Finally, it has a wider operating temperature range, which allows it to be used in harsh environment conditions.

Conclusion

The VS-STT170M14MPBF is an ideal choice for power supplies that require highly efficient, cost-effective and reliable solutions. Its wide range of advantages, such as low voltage drop, high surge current, small size, and wider operating temperature range, make it suitable for use in a variety of application fields including military, aerospace and industrial systems. Moreover, its simple and reliable bridge rectifier working principle makes it ideal for use in a range of power conversion and battery charger applications.
