Introduction
A bridge rectifier is an electronic circuit device widely used in the field of power electronics, mainly used to convert alternating current (AC) to direct current (DC). Its simple structure and high efficiency have made it widely used in power supplies, electronic devices, and renewable energy systems. With the continuous advancement of technology, the design and application of bridge rectifiers are constantly evolving, and related patented technologies are emerging. This article aims to analyze the basic principles of bridge rectifiers, important patents related to the industry, their market impact, and explore future trends and challenges.
Part One: Basic Principles of Bridge Rectifiers
1.1 Working Principle of Bridge Rectifiers
The basic working principle of a bridge rectifier is to use a bridge circuit composed of four diodes to rectify both the positive and negative half cycles of the AC power into DC. The basic concept of rectification is to convert the waveform of AC power into a waveform of DC, eliminating the current of the negative half cycle, so that the output current is always positive.
The circuit structure of the bridge rectifier is as shown in the diagram, with four diodes connected at the two ends of the power source to form a closed loop. During the positive half cycle of the AC, D1 and D2 conduct, and the current flows through the load; during the negative half cycle, D3 and D4 conduct, and the current still flows through the load. In this way, the output voltage of the rectifier is always positive, completing the rectification process.
During the rectification process, the change in current and voltage is an important characteristic. The output voltage waveform exhibits the characteristics of pulsating DC, which usually needs to be further smoothed by a filter circuit to meet the requirements of practical applications.
