Abstract

The invention discloses a conduction time generation circuit for a power supply converter, and a power supply converter. According to the invention, a band-pass filtering circuit is additionally arranged, DC components of second reference signals are equal to first reference signals, a differentiating circuit has a differential effect, can rapidly react to change of output voltages, timely performs feedback and adjustment, and the change trench of AC components of the second reference signals is opposite to the change trench of the output voltages. According to the invention, in case of abrupt change of the output voltages, the second reference signals can timely perform feedback and adjustment so as to reduce influences generated due to the abrupt change of the output voltages and enable the output voltages to be rapidly recovered to be constant.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a turn-on time generating circuit for a power converter and the power converter. Background technique [0002] The power converter realizes the expected output through the voltage conversion of the power stage circuit, and keeps the output voltage constant, that is, adjusts the output voltage by controlling the conduction state of the main power switch tube in the power stage circuit. Therefore, it is necessary to sample the output voltage and implement feedback to control the on-off state of the main power switch tube according to the comparison result of the output voltage and the corresponding reference voltage. [0003] In the fixed on-time working mode, the output voltage sampling signal is error-processed with the corresponding reference voltage to obtain a feedback compensation signal, and the feedback compensation signal is compared with the current sampling sig...
