Abstract
The thyristor current voltage-stabilized source is an AC-DC converter. Which changes AC to DC by Full Bridge converter .Its designed key point is the higher transformed effciency and the output DC voltage maintentance is stable .
This article introduces a voltage-stabilized source .Which trigger converters poses with KJ004 and KC41C and its three phase Full bridge controlled rectifier is posed with thyristor .This power source greatly enhances the current transformed efficiency and the output
Voltage-stabily,has solved the existing system existence problem in the certain degree, and thus enhances the whole system’s performance characteristic. This article studies the power to obtain from the main circuit ,analyzes the trigger pulse characteristic which the three phase bridge rectifier input level and its needed to determine the main circuit and the triggert circuit .Obtained from the output voltage stable aspect
increased auxiliary circuit ,voltage regulator ,current regulator and flitter circuit and so on .Obtained from the protection crystal thyratron
part aspect,increated the voltage electric protection circuit and so on .
This power’s output voltage can move from 10V to 100V ,has a wider accent to press the scope, its output voltage is stabilized when the perturbation in the situation .This power can satisfy the production and the life need.
Keywords: Thyristor Full-bridge controlled rectifier ;Trigger Converter ;Voltage-stabilized source .
