Open the CIPO recordAbstract From the Canadian patent
A switching regulator which substantially suppresses effects on the output voltage of noise in a direct input voltage includes a direct voltage source for producing an input voltage and output, and a controllable electronic switch connected between the voltage source and the output, an inductance connected between the voltage source and the switch, a pulse with modulator for controlling the switch, a first saw tooth signal producing device for supplying to the pulse width modulator a saw tooth signal and, a device for producing a current proportional voltage which is proportional to current through the inductance. This current proportional voltage is supplied to the pulse width modulator. …
