Operation principle of the present utility model:
Before introducing operation principle, the utility model should at first be described because of being subjected to the designing requirement of supporting automobile integrated circuit, under the different operating state, binding post L and binding post one, two ends are respectively by two kinds of different electrical power power supplies.That is: when generator when generating end, be by battery feed by the generating indicator light to the power supply of L end.When generator for electricity generation voltage be raised to 〉=during 4V, the L end changes by generator powered.
The circuit working principle: initial generator when generating end, connect battery feed, the electric current generator indicator light (in external circuit of the present utility model) of flowing through connects the post power supply to L.This electric current minute two branch roads are popular.One, by the L point through resistance R
4, series diode D
1Form the grid voltage boostrap circuit to T
1The fet gate charging.When gate capacitance charges voltage is raised to V
GDuring 〉=4V, field effect transistor T
1The beginning conducting.Immediately another branch current, flow through generator field coil to the F binding post by the L binding post, again through field effect transistor T
1D, the S utmost point connect post to negative pole, supply with one faint outer electric current of encouraging of magnetic field.But the L point voltage is by V this moment
L〉=4V drops into below the 0.4V immediately.(because of outer excitation system resistance, end resistance about 120 Ω on the L binding post, under resistance be 4 Ω.When cell voltage is the 12V power supply, so the L point is got voltage V
L≈ 0.4V) the charge voltage V that stores because of fet gate electric capacity
GStill be more than the 4V, V
GTurn to the trend of L point discharge immediately.Because D in the grid voltage boostrap circuit is arranged
1The effect that diode reverse stops keeps V
G〉=4V keeps rising, field effect transistor T
