Applications

The VS-50PF80 is designed for use in DC power applications, such as power supplies, power factor correction, DC-DC voltage boost, AC-DC conversion and inverter DC link energy storage. It can also be used in applications such as power converters, renewable energy, motor control and lighting systems.

Working Principle

The VS-50PF80 works on the principle of rectification, which is the process of converting alternating current (AC) into direct current (DC). It does this by using diodes to allow current to flow only in one direction. This is achieved by connecting one or more diodes in a bridge or half-bridge configuration across the AC source. When the power source is in the “positive” cycle, current will flow through the diode and into the load. When the power source moves into the “negative” cycle, the diode will not allow for the current to flow and will instead act as an open circuit, preventing any current from passing through. This process effectively ‘rectifies’ the AC waveform, and results in a consistent DC waveform being output from the bridge. The VS-50PF80 is specifically designed to allow for high frequency operation, and to ensure a high power efficiency.

Conclusion

The VS-50PF80 is a robust, reliable and energy-efficient diode rectifier designed for DC power applications such as power supplies, power factor correction and inverters. It is constructed from a very robust and reliable metallic package and uses a rectification process to convert AC into DC. The VS-50PF80 is ideal for a variety of applications as it features a wide operating frequency range and an optimized power efficiency of >95% typical.
