trigger voltage
1.By studying different kinds of factors which affected the synchronization, the suitable experimental conditions for the operation of the pumping source have been obtained, and these conditions may be thought as the voltage of higher than 15kV, the pressure of 1-1.5 atm in the case of N2:Ar=3:7, the trigger voltage of higher than 30kV with the risetimeabout 10ns.
3.Using the Digital Technology improves the performance traditional thyristor welding machine, according to the characters of the double inverse star from rectifier circuit, set the parameters with micro-controller accurately, design the dependable trigger circuit, lead the feedback of voltage for the operation program, so the voltage of main circuit be carried out very steadily.
7.Delphi is adopted to program the whole software with assembly language embedded. Among them, Delphi is adopted to code user program, in which user can set test parameters, select test type and test voltage level, determine channels whether active or not to output trigger pulse. Serial port communication function is also included.
