S1BLHRUG

Diodes - Rectifiers - Single

A Single Bilateral Half-wave Rectifier with Unilateral Gain or S1BLHRUG is a type of rectifier that works based on a two-stage process. It is used for smaller systems or when a high-speed response is needed. The diagram below details the two stages of the process:

The first stage is the half-wave rectification process. This process is carried out when a single direction current is being directed through the device. In this stage, the electric field is blocked in the opposite direction and the voltage with the electric current is boosted. The output voltage is larger in magnitude than the input voltage as the rectifier is designed to convert an alternating current (AC) to a direct current (DC). The second stage is the unilateral gain operation. This is achieved when the gain element is included in the rectifier system to can amplify the current by scaling the output voltage further. During this process, the nonlinear gain components allow for higher current flow values and a power gain for the rectifier. The unilateral gain is necessary for the half-wave rectifier to boost the output voltage. The end result of the two stage rectifier system is a stronger output current over greater distances and a reduced voltage variation over time. The popularity of the single bilateral half-wave rectifier with unilateral gain is for uses where a reliable and quick response is needed, such as in computer motherboards, electronic products, and office equipment.

Advantages

• High output voltage with minimal ripple
• High power gain that keeps the output voltage steady
• Reduced voltage drops over long transmission lines
• Excellent efficiency
• Faster response time than other rectifiers
• Low cost
• Long lasting

Disadvantages

• It can generate harmonic distortion due to the nonlinearity of the system
• The total current gain is limited
• It only works with one direction of current

The single bilateral half-wave rectifier with unilateral gain has become a mainstay in electronic systems because of its many advantages. Its low cost, enhanced performance, and high efficiency make it an ideal solution for small and large scale electrical systems.
