AC to DC Calculator
Calculate AC to DC conversion for power supplies, chargers, and electrical systems. Understand voltage, current, power factor, and efficiency in AC-DC conversion.
Step 1: AC Input Parameters
Understanding AC Parameters
AC Voltage is measured in RMS (Root Mean Square). Power factor indicates efficiency of power usage. Typical power supplies have PF between 0.6-0.95. Higher PF means better efficiency.
Step 2: DC Output & Conversion
About AC-DC Conversion
AC to DC conversion typically involves rectification (converting AC to pulsating DC) and filtering (smoothing to pure DC). Efficiency varies by method: switching supplies (85-95%), linear regulators (40-60%).

Power Conversion Analysis
AC-DC Conversion Formula
DC Voltage ≈ AC Voltage (RMS) × √2 × Efficiency
For full-wave rectification, DC voltage is approximately 1.414 times the RMS AC voltage minus diode drops and losses. Actual output depends on filtering and regulation.
