Title:
ダイオード導通デューティ・サイクルを調節する装置
Document Type and Number:
Japanese Patent JP5424442
Kind Code:
B2
Abstract:
A power converter control method and apparatus is disclosed. A control circuit (115)for use in a power converter (100) according to aspects of the present invention includes a clock signal generator coupled to generate a clock signal to control switching of a power switch (105) to be coupled to the control circuit (115). Feedback circuitry is coupled to receive a feedback signal (114), which is representative of an output of a power converter (100) during a feedback portion of an off time of the power switch. The feedback circuitry is coupled to respond to the feedback signal (114) to control the clock signal generator to regulate a duty cycle of the feedback portion of the off time of the power switch (105) as a proportion of a total power switch switching cycle period.
