摘要： Disclosed is a synchronous rectifier type DC-to-DC converter capable of preventing an increase in losses occurring when a rectifier synchronous rectification switch and a flywheel synchronous rectification switch, which are responsible for rectification on the side of a secondary winding of a transformer, are turned on simultaneously, and the destruction of FETs or windings due to large currents. The DC-to-DC converter comprises a transformer, a primary switching device connected in series with a primary winding of the transformer, a control circuit for controlling turning on or off of the primary switching device, a rectifier synchronous rectification switching device, and a flywheel synchronous rectification switching device, and converts a voltage of a DC power source into another voltage. The DC-to-DC converter further comprises a rectifier rise delay inductive device connected in series with the rectifier synchronous rectification switching device and a flywheel rise delay inductive device connected in series with the flywheel synchronous rectification switching device.

摘要： A synchronous rectifying type DC-DC converter including an auxiliary winding, provided on a secondary side of a transformer, for supplying voltages assuming polarities opposite to each other to control terminals of a rectifying switch and of a fly wheel switch, and the rectifying switch and the fly wheel switch are so constructed as not to be turned ON/OFF by a voltage generated on a supply path of an electric current to a load from a secondary winding of the transformer. When connecting a plurality of DC-DC converters in parallel and operating these converters in parallel, an output of any one of the converters stops, and, even if outputs of the other DC-DC converters are inputted to the DC-DC converter concerned and the electric current flows into the current supply path, a voltage based on the above current is not applied to control terminals of the rectifying switch and of the fly wheel switch. The rectifying switch and the fly wheel switch are not therefore turned ON. Accordingly, a large quantity of electric current is prevented from flowing into the DC-DC converter concerned.

摘要： The DC output of a power conversion unit is controlled based on a pulse signal generated by a PWM unit. An operations unit detects an output current Iout, and determines the operation mode of a load based on the detected current value. When the output current Iout is weak, a value smaller than usual is written to a cycle register. The PWM unit generates a pulse signal according to the data stored in the cycle register and an on-time register.
