It is uncertain to be increased and uncertain on the component for being present in all installations, and therefore it is necessary to ensure that final appliance system
(1) all variations that may be present are resistant to.In order to make these variation do not cause too greatly with too apparent voltage change, by leakage inductance
(Lr) resonance frequency caused by (fo) should be sufficiently far from the resonance frequency (fp) as caused by magnetizing inductance (Lm).In order to make this two
A resonance frequency (fp) and (fo) are sufficiently far from, and emit induction coil (4) and induction receiving coil (5) is dimensioned, so that +/-
The frequency variation of 5kHz causes the variation of the maximum +/- 10% of the output voltage especially voltage (Vo) of air type transformer.
Therefore by the scale cun of air type transformer and the excitation in fixed frequency to induction generator (2),
The output section of transformer obtains voltage, especially voltage (Vo), the voltage stabilization and with the load (R) of appliance system (1)
Change unrelated.
