The output Current of the rectifier welder of magnetic amplifier type changes significantly with the changing of the supply volage.It is known that the change of output current influences the performance of the welder of this type.In this paper,a compensatory link compensating the fluctuation of the supply voltage and a link of negative feedback were inserted into the excitation circuit of magnetic amplifier of the welder,the insert makes that the exciting current increases dully with a decrease in supply voltage and decreases correspondingly with an increse in supply votage.So that,the change of output current is very small as the supply voltage fluctuates,hence the stability of the output current is improved. In this paper,the working principle of the excitation circuit and tha analysis of experimental data have been given.The aforesaid ex —citation circuit has been applied to the LH—80 plasma arc welder made by us,the output current of this welder varies only withih±2% whilst the supply vpltage fluctuates ±10.

In this paper, the voltage fluctuation characteristics are experimentally studied for a silver deposition system. At the same time, the influences on voltage fluctuation of the degree of expansion of fluidized bed, of the voltage difference between collector and counter, and of the fluidization state are investigated. The conduction mechanism proposed in Part( I ) is corroborated experimentally.The experimental results show that there are two manners for the particle and electrolyte voltage fluctuations, one of high frequency but low amplitude and the other of low frequency but high amplitude. When slugging or channeling appears, the particle voltage and the electrolyte voltage fluctuate irregularly while the overvoltage has essentially no irregular fluctuation. The influence of the voltage difference between collector and counter on the voltage fluctuations is rather pronounced. When the voltage difference is lower than about 1V for the reactor used there are essentially not low frequency, high amplitude voltage fluctuations. When the voltage difference is greater than about 1V, the low frequency, high amplitude voltage fluctuations for both the particle and electrolyte become more and more remarkable.
