Abstract
A new computer controller is disclosed for controlling the output voltage of a SCR controller to a load. The computer controller includes a computer unit comprising a first pulse generator, a central processing unit, a first voltage comparator and a digital analog converter, and a control unit controlled by the computer unit and connected to the load through the SCR controller and consisting of a second pulse generator, an integrator circuit, a second voltage comparator, a turn-on circuit and a turn-off circuit.
Claims3
A computer controller comprising a computer unit, a control unit, a SCR controller, a .pi. type filter and a load, said .pi. type filter having a first node connected to said SCR controller and a second node connected to the load, said SCR controller being connected to the control unit, wherein said computer unit comprises a first pulse generator, a central processing unit connected to an output from said first pulse generator, a first voltage comparator comparing an output from said .pi. type filter with a standard voltage at input terminals and having an output connected to said central processing unit, a digital analog converter connected to an output from said central processing unit;
- and wherein said control unit comprises a second pulse generator, an integrator circuit connected to an output from said second pulse generator, a second voltage comparator connected to an output from said integrator circuit and also connected to an output from said digital analog converter, a turn-on circuit connected to an output from said second voltage comparator and a turn-off circuit also connected to said output from the second voltage comparator;
- said .pi. type filter being an inductance-capacitance controlled to convert a square wave voltage to a DC voltage;
- said load having load characteristics such as resistance, inductance, capacitance and battery.
