    摘要: A power supply start up booster circuit for providing an increased startup voltage for a switch mode control integrated circuit including a boost portion for combining a first input voltage that has a predetermined minimum value and a second input voltage that transitions from 0 volts to the predetermined minimum value to make a minimum threshold voltage, a control portion having an integrated circuit for using the minimum threshold voltage to temporarily provide a voltage input at the integrated circuit, and an output portion for providing a permanent voltage input at the integrated circuit and an output supply voltage to an external circuit.

    摘要: Apparatus is disclosed for controlling the regulating inductance of a power supply by applying across a control winding mounted on the same core a voltage having a volt-second product proportional to the difference between a desired output voltage and the actual output voltage so that the frequency of response is the same under all operating conditions. In a preferred form, the apparatus is incorporated in a power supply having a source of DC pulses that are rectified to produce the output voltage and the volt-second product of the voltage applied across the control winding is proportional to the difference between the detected value of said pulses and a control voltage that is related to the difference between the actual output voltage and the desired value.

    摘要: A circuit for regulation of a D.C. output voltage in a switching power supply. The circuit contains a control transformer having primary, secondary and control windings. The output of the circuit is connected from the primary and secondary windings and is controlled by a switching element connected from the control winding. The circuit output error is provided to duty cycle modulation circuitry which varies the duty cycle of the switching element, thereby controlling the output voltage level.
