The triode voltage steady circuit

Published:2011/6/19 1:02:00 Author:Seven | Keyword: voltage steady circuit

The input voltage of the emitter output circuit is fixed at VZ, so the output voltage VO=VZ-VBE is also fixed. When the grid voltage is fluctuating, as VZ is almost still and VO is the same, the change of VI is adjusted by VCE, so the triode is called the adjusting pipe. When RL changes and it causes the fluctuation of IO, as lone as the △IZ is in the normal range of the stabilovolt tube, VZ will remains the same, i.e VO is almost stable. The fluctuation of the circuit output current can be expanded to （1+β）△IZ, so it is also called the enlarging voltage stable diode circuit.   (View)
