Defining An Active Rectifier In A Power Driven World
An active rectifier provides the palpable means to improve the overall efficiency of rectification by the replacement o diodes with switches that are actively controlled such as transistors. Ultimately, an active rectifier can be made to cause a huge drop in voltage across transistors, which means a noticeable reduction in power loss and a huge gain in efficiency, making active rectifiers both a cost effective and green solution. The only downside is that with high currents, sometimes the voltage drop can be lower than that of a diode. The problem is easily dealt with however, by using several transistors, typically parallel to each other, to effectively reduce the current flowing through each one. Green solutions are in, and anything that can reduce power consumption while raising efficiency is an important investment in the future of mankind, so utilizing active rectifiers is a step in the right direction.
