The AC to DC Converter Calculator helps convert an alternating current (AC) voltage into its approximate direct current (DC) equivalent after rectification. Users can select between half-wave, full-wave, and bridge rectifier types. The tool calculates the DC output voltage based on the RMS input, diode voltage drops, and rectification method. It also gives insight into the ripple quality, showing how smooth the DC output will be. This calculator is perfect for understanding power supply design and rectifier performance in electronics.
