helvågstransformatorer
Helvågstransformatorer, also known as full-wave transformers, are a type of electrical transformer specifically designed for use in full-wave rectifier circuits. Unlike simpler half-wave rectifier circuits that only utilize one half of the alternating current (AC) waveform, full-wave rectification makes use of both the positive and negative alternations of the AC input. Helvågstransformatorer facilitate this by providing a center-tapped secondary winding. This center tap acts as a common reference point. When connected to a full-wave bridge rectifier or a center-tapped full-wave rectifier with two diodes, the helvågstransformator allows current to flow in the same direction through the load during both halves of the AC cycle. This results in a more efficient conversion of AC to direct current (DC) with less ripple than a half-wave rectifier. The output DC voltage from a full-wave rectifier using a helvågstransformator is also twice that of a comparable half-wave rectifier, assuming the same transformer secondary voltage. These transformers are commonly found in power supplies for electronic devices where a more stable and efficient DC output is required.
