Benefits of technology

The inventor proposes that it should have two circuits: one for AC signals (AC) while another for DC signals. This design allows for simpler and less expensive components than existing designs without sacrificing their functionality or performance.

Problems solved by technology

This patented technical solution described for improving the performance and efficiency of an electronics system's power supply unit involves adding two inputs: either manual or auto-switching mode, allowing it to quickly switch between different modes based on any changes made during normal operations without causing potential equipment malfunctions.

Abstract

A power supply apparatus including a first rectifier switching circuit and a second rectifier switching circuit is provided. The first rectifier switching circuit is coupled between a live wire terminal and a neutral wire terminal of a first AC power and a first contact and a second contact. The second rectifier switching circuit is coupled between a live wire terminal and a neutral wire terminalof a second AC power and the first contact and the second contact. The first rectifier switching circuit performs rectification on the first AC power and thereby provides a rectified power to the first contact and the second contact when a status of the first AC power is normal. The second rectifier switching circuit performs rectification on the second AC power and thereby provides the rectifiedpower to the first contact and the second contact when the status of the first AC power is abnormal.
