A transformer is an electrical device that can transfer electrical energy from one circuit to another through electromagnetic induction. In the case of a forward transformer, the transformer is designed to transfer energy in a forward direction, from the primary circuit to the secondary circuit.
A 100W forward transformer is designed to handle up to 100 watts of power in the forward direction. This means that the transformer can handle up to 100 watts of power being input into the primary circuit and transfer that energy to the secondary circuit.
The transformer works by using two coils of wire, a primary coil and a secondary coil, wrapped around a magnetic core. When an alternating current (AC) voltage is applied to the primary coil, it creates a magnetic field that expands and collapses around the magnetic core. This expanding and collapsing magnetic field induces an AC voltage in the secondary coil through electromagnetic induction.
The amount of energy transferred from the primary circuit to the secondary circuit is determined by the number of turns in each coil and the ratio of the voltage in the primary circuit to the voltage in the secondary circuit. This is known as the turns ratio.
In a forward transformer, the primary circuit is connected to the power source and the secondary circuit is connected to the load. The transformer steps down the voltage from the power source to the load and increases the current to match the load requirements.
In summary, a 100W forward transformer works by transferring electrical energy from the primary circuit to the secondary circuit through electromagnetic induction. It steps down the voltage from the power source and increases the current to match the load requirements.
