.The secondary watts of a transformer with a primary of 1,200 va and an efficiency of 92% is watts.The primary va of a transformer with a secondary of 1,600 watts and an efficiency of 88% is va. Power Factor There is also some loss in power in transformers due to power factor. You remember that transformers use coils of wire.

Size of Secondary Wire for Transformer Design Calculation. A2=(4.2 A/ 2.3 ) = 1.83 mm2. From the standard copper wire, table it can be seen that wire of this thickness is of 15 gauge. So, Transformer Design Calculation for secondary winding we need 15 gauge wire. Hence, Secondary Wire = 15 AWG. Secondary Number of Turns.

Suppose you make a transformer with an output power of 300 watts, then 300watt / 220v = 1.4Amper and see the wire that can be used with a 50KHz frequency in the AWG table above. For example the wire used is 0.5mm then 1.4 Amp / 0.5 = 2.8 or rounded down or upward to be 2 or 3 double wire and of course the coil must be 2 or 3 times more primary wire used than secondary because Vin 12v then 300w.
Transformer Calculation v0.1 is program for calculating number of coils and wire thickness.
If you have some experience in assembling transformers, then this program is perfect for you.
If you don’t known anything about assembling transformers, please don’t use calculations from this program for building your own transformer!
Wrong calculation can do damage to your electric device attached to electric network, and IT CAN KILL YOU !!!
You can still use this program to determine how big EI core of transformer must be, if you plan to buy transformer. Note there are lot of transformers that are hybrids, so if you need transformer for amplifire buy right sized transformer. Hybrid transformer are ordinarily small and under high load it can overheat.
This program can calculate values only for standart transformer core, that’s “W” and “U” profile of core.
Toroid transformers (ring profile of core) and others aren’t supported.
Transformer IE core square dimension:
- Height and Width of core intersection.
- Maximum power of core.
Primary coil – parametars:
- Input voltge of transformer.
- Button for adding wanted voltage to list.
- List of selected input voltage.
- List of calculated input amperage.
- Current calculated power.
Secondary coil – parametars:
- Output voltge of transformer.
- Output amperage of transformer.
- Add/Change button for adding/changing wanted voltage and amperage to/in lists.
- List of wanted output voltage.
- List of wanted output amperage.

All modern electronic flash units often called photographic strobes are. All of these use the triggered. The typical electronic flash consists of four parts 1 power supply. An electronic flash works as follows. The energy storage capacitor connected across the flashtube is charged. V typical power supply. This is either a battery or AC adapter.

A ready light indicates when the capacitor is fully charged. Most. monitor the voltage on the energy storage capacitor. However, some. detect that the inverter or power supply load has decreased indicating. Normally, the flashtube remains non conductive even when the capacitor. A separate small capacitor e.
