摘要： An example controller for use in a power supply in accordance with the present teachings includes a drive signal generator, a jitter signal generator and a compensator signal generator. The drive signal generator is coupled to output a drive signal having a switching period and a duty ratio to control switching of a switch that is to be coupled to the controller. The jitter signal generator is coupled to provide a jitter signal, where the switching period of the drive signal varies in response to the jitter signal. The compensator signal generator is coupled to provide a compensator signal responsive to the jitter signal, where the duty ratio of the drive signal is varied in response to the compensator signal.

摘要： A DC/DC converter includes a switch, an inductor, a capacitor, a resistor, and a voltage divider. The switch is coupled to the input voltage. The inductor is used for coupling the first switch to an output node of the DC/DC converter so as to generate the output voltage at the output node. The capacitor is coupled to the output voltage. The resistor is coupled to the capacitor in series, and is coupled to ground. The voltage divider is coupled across the capacitor so as to reduce the zero frequency of the DC/DC converter.

摘要： A regulating method and device are provided for compensating variations in a supply voltage to a microwave transmitter which includes a grid pulsed traveling wave tube. The devices includes a first capacitor and, in series with the first capacitor, a second capacitor connected to a control circuit. The control circuit, substantially in opposition to a current representing current variations through the first capacitor, conducts current through the second capacitor. The current through the second capacitor generates a compensation voltage which, together with a capacitor voltage across the first capacitor, forms the supply voltage.
