Abstract
A variable DC-DC converter includes a no-load voltage clamp in which a rectified, filtered, and loaded control signal drives a switch. The switch switches in a load resistance across the output terminals of the converter when the output terminals are unloaded or lightly loaded. Due to a combined rectification, smoothing, and filtering operation of the control signal circuit, the control signal provides a steady voltage of the output voltage selected by a user of the converter based on predetermined output requirements. The control signal is therefore not subject to the voltage spikes that the main output is subject to. The circuit compares the control signal to the output voltage, and switches in the load resistance when the voltage at the output rises above the control signal.
