PowerECal - Power Supply Tool

PowerECal - Power Electronics, Power Supply and Magnetic Engineering Calculator includes magnetic builder, the magnetic formulas calculation, units conversion and wires conversion tables. It's a very useful tool for power electronic engineers.

Magnetic Builder:
Magnetic Builder is a useful magnetic design software. It is a tool for user to create his/her own magnetic component (inductor and transformer) by selecting different ferrite core, bobbin type and winding method. Engineering drawing will be automatically produced to reduce user work load.

Magnetic Properties:
Transformer / Inductor / Magnetic flux density Calculator
- which can calculate peak flux density(Bp) against peak current Ip or voltage Von and duty cycle Don;
Magnetic Unit Conversion
- The conversion of MMF magnetomotive force between Oe and A/m, and flux density between T and G;

Air Flow:
Volume & Velocity Unit Conversion
- The conversion among ft³/s, m³/s, cubic feet per minute(cfm, ft³/min), million gallon per day(mgd) and Liter/s;
- The conversion among mile per hour(mph, mile/hr), km/hr, m/s, feet per second(ft/s) and feet per minute(ft/min);
Temperature Rise vs Air flow Calculator
- which can calculate Velocity and Volume needed for the air flow through a box. By inputting cross section dimension, power dissipation(Pd)inside the box and temperature rise(dT) of the outlet air flow, result can be shown according to the provided illustration.

Wire Gauge sizes table:
- According to wire numbers, list the different wire diameters in SWG(mm) and AWG(mm).

PCB Copper Trace Thickness Unit Conversion：
- The conversion among Ounce(oz), mil and milimeter(mm);

Energy, Pressure and Power Unit Conversion:
- The conversion among Joule(J), calorie(cal) and British therm unit(Btu);
- The conversion between bar and N/m²;
- The conversion among horse power(hp), ft lb/s, British therm unit per second(Btu/s), British therm unit per hour(Btu/hr), kW and Watt(W);

Temperature Unit Conversion:
- The conversion among degree Celsius(C), degree Fahrenheit(F) and Kelvin(K);

Dimension & Weight Unit Conversion:
- The conversion among cm³, inch³, Liter, m³ and gallon;
- The conversion among Pound(lb), kg, Newton(N), ton, Ounce(oz) and g.
