摘要： A first softstart signal indicates operation in a load phase for a boost rectifier and a second softstart signal indicates operation in a pulse drive phase which follows the load phase. A rectification transistor is actuated for the duration of the load phase in response to the first softstart circuit to generate a rising output voltage. The rectification transistor is further repeatedly actuated during the pulse drive phase in response to the second softstart circuit to generate a boosted output voltage. A first transistor coupled between a first conduction terminal and a body terminal of the rectification transistor is actuated, and a second transistor coupled between the body terminal and a second conduction terminal of the rectification transistor is deactuated, during the load phase. The first transistor is deactuated, and the second transistor is actuated, during the pulse drive phase.

摘要： A power converter includes an input and an output with an energy storage circuit and a power switching circuit coupled between the input and the output. A feedback circuit generates a feedback voltage which is differentially compared to a reference in an error amplifier circuit to generate an error amplification signal. A comparator circuit generates a control signal for controlling on/off of the power switching circuit based on a first comparison signal related to the error amplification signal and a second comparison signal related to a charging current of the energy storage circuit. A regulating circuit is coupled between an output of the error amplifier circuit and an input of the comparator circuit for receiving the first comparison signal, the regulating circuit is configured to couple a voltage compensation signal related to an input voltage received by the input to an output of the error amplifier, so as to reduce a variation amount of the error amplification signal when the input voltage varies.

摘要： A constant-frequency current-mode-controlled boost converter circuit provides slope compensation of an inductor current, reduces reverse inductor current in light output load conditions, and reduces oscillation between a discontinuous current mode and a continuous current mode by enabling or disabling an inductor current threshold. The constant-frequency current-mode-controlled boost converter circuit is efficient and stable in light, medium, and heavy output load conditions.
