Abstract
The d.c. voltage converter employing pulse width control with current and output voltage feedback, and giving a controlled output voltage, suffers from the disadvantage that any extension of the output pulse length beyond half a period to maintain the output voltage results in instability. This deficiency is eliminated by introducing a modifying signal into the reference circuit. The output voltage is compared with a voltage comprising a constant reference (Uref), a load current dependent term (UR1), and a saw-tooth voltage in phase with the switching frequency (1/T). The modification allows a large increase in pulse width without instability, and is applicable to most pulse width modulated regulators operating at constant frequency.
