Abstract

A post regulated switching regulating d.c.-to-d.c. converter with pulse width modulation for limiting the regulated output voltage to a magnitude which is just slightly higher than the normal regulated value if the regulation capabilities of the converter are exceeded either by increasing the input voltage above a certain amount for a given load or by decreasing the load resistance below a minimum value.
