Hybrid Solar Inverter Dc To Ac

NX series hybrid solar inverter dc to ac 12v 24v 

     If the transformer is only connected to the power supply side, and the secondary load is not connected to the circuit, then the secondary current of the transformer is I=0, and this working state is the no-load operating state of the transformer. According to Lenz's law, if the excitation current is too small to be ignored, the primary voltage drop IZ of the winding can also be ignored. At this time, the induced electromotive force E on the primary side of the transformer and the power supply voltage can be considered to be equal in magnitude and opposite in direction, and there is the following voltage balance relationship : U=-E, U=E

According to the law of electromagnetic induction, the value of the induced potential is determined by the rate of change of the magnetic flux, so there is the following relationship:

,

The effective value of the induced potential changing according to the sinusoidal law is equal to its maximum value divided by √2, so, there is

The ratio of the primary voltage to the secondary voltage of the transformer is called the voltage ratio (referred to as the transformation ratio).

so

Therefore, the transformation ratio of the transformer refers to the ratio of the primary voltage to the secondary voltage when the transformer is no-load, that is, the ratio of the number of turns of the primary winding to the number of turns of the secondary winding.
