A one-pulse controlled rectifier typically implies a half-wave converter.
A rectifier is an electrical circuit that converts alternating current (AC) to direct current (DC). In a half-wave rectifier, only one-half of the AC waveform is converted into DC. This is achieved by using a diode that conducts current in only one direction. The diode allows the positive half of the AC waveform to pass through while blocking the negative half.
A one-pulse controlled rectifier is a specific type of half-wave rectifier where the conduction of the diode is controlled by a single pulse. This pulse can be generated by various means, such as a triggering circuit or a control signal. The diode conducts current for the duration of the pulse, allowing the corresponding portion of the AC waveform to be rectified.
In contrast, a full-wave rectifier converts both the positive and negative halves of the AC waveform into DC. This is typically achieved using a bridge rectifier circuit, which consists of four diodes. The four diodes are arranged in a bridge configuration and allow the current to flow in the desired direction regardless of the polarity of the input AC waveform.
Therefore, when the term "one-pulse controlled rectifier" is used, it generally refers to a half-wave rectifier.
