Abstract:
1. A valve control system comprising: a first valve and a second valve; a power sensor circuit coupled to the second valve, the power sensor circuit configured to produce a feedback signal responsive to a measurement of power associated with the second valve; a logical component having a first input, a second input, and an output, wherein the output is a logical AND of the first and second inputs, the first input being coupled to a first valve signal, and the second input being coupled to the feedback signal; a first transformer driver coupled to the output of the logical component; a second transformer driver coupled to a second valve signal; a first transformer coupled to an output of the first transformer driver; a second transformer coupled to an output of the second transformer driver; a first rectifier circuit coupled to the first transformer and the first valve; and a second rectifier circuit coupled to the second transformer and the second valve.
