Ideal for electronics hobbyists, engineers, and anyone needing precise electrical calculations. Optimize your power supply efficiency today!
Formula:
The calculator uses the following fundamental electrical formulas to convert AC input to DC output, accounting for efficiency loss:
- AC Apparent Power (S) = VAC × IAC (Volts-Amperes, VA)
- AC Real Power (PAC) = S × Power Factor (Watts, W)
- DC Output Power (PDC) = PAC × (Efficiency / 100) (Watts, W)
- DC Output Current (IDC) = PDC / VDC_target (Amperes, A)
Where:
- VAC = AC Input Voltage (Root Mean Square, RMS)
- IAC = AC Input Current (RMS)
- Power Factor = A dimensionless number (0 to 1) representing the ratio of real power to apparent power.
- Efficiency = The percentage of AC real power successfully converted to usable DC power.
- VDC_target = Your desired DC Output Voltage.
- IDC = The achievable DC Output Current at the target voltage.
