ABSTRACT:
A power regulating device which maintains a constant rms voltage across a load by periodically interrupting the application of voltage to the load for a predetermined number of cycles. To accomplish this, a functional solution to the equation which describes the relationship between the rms line voltage developed across the load and the rms voltage of a desired control set point is continuously provided. The solution of this equation is obtained by squaring a sampling of the applied load voltage, subtracting the square of the desired control voltage, and then integrating over time the difference therebetween. When the resultant time integral reaches a predetermined constant value, the voltage applied to the load is interrupted for a predetermined number of half or full cycles.
