Half Wave
A "Half Wave" refers to a type of waveform that only includes one half of a complete cycle. In electrical engineering, this concept is often applied in the context of AC (Alternating Current) signals, where the waveform alternates between positive and negative values. A half wave rectifier, for example, allows only one half of the AC signal to pass through, effectively converting it into a pulsating direct current.
This method is commonly used in power supply circuits, where it is essential to convert AC to DC (Direct Current) for various electronic devices. While half wave rectification is simple and cost-effective, it is less efficient than full wave rectification, which utilizes both halves of the AC cycle.
