Specifically, the voltage stabilizing process of supply voltage adjustment portion 40 is：
When by dipole inversion portion 30 convey Lai voltage U1 raise when, the voltage U2 of parallel resistance 43 is increased.Due to
Voltage-stabiliser tube 42 is in parallel with parallel resistance 43, and therefore, the electric current increase of voltage-stabiliser tube 42, the electric current I for flowing through resistance R2 also increases therewith,
So that resistance R2 voltage drop increase, so as to counteract voltage U1 rise so that the voltage U2 of parallel resistance 43 keeps constant.
That is, the voltage exported via supply voltage adjustment portion 40 is kept stable.
When by dipole inversion portion 30 convey Lai voltage U1 reduce when, the voltage U2 of parallel resistance 43 declines therewith.Due to

When the external voltage of mobile communications device output is more than or equal to predetermined value, that is to say, that current movement is led to
T unit is the strong mobile phone of power supply capacity, now, main electrical current path is formed between dipole inversion portion 30 and voltage-stabiliser tube 42, also
It is to say, the electric current exported by the cathode output end 33 in dipole inversion portion 30 mainly flows back to cathode output end 34 by voltage-stabiliser tube 42
In.
When the external voltage of mobile communications device output is less than predetermined value, that is to say, that current mobile communications device
