Controller for power converter

A controller for a power converter. The power converter comprises a converter-switch and a converter-inductor. The controller comprises a controller-output-terminal configured to provide a switch-control-signal for the converter-switch, a comparator and a delay-block. The comparator can provide a comparator-output-signal that has a comparator-output-state dependent on whether or not a sensed-signal is greater than a reference-signal, wherein the comparator-output-state can take a first-state-value or a second-state-value. The delay-block can: set a time-delay-value based on: (i) a voltage across the converter-inductor; start a timer when the comparator-output-state changes; and cause a change in the switch-control-signal when the timer reaches the time-delay-value. 种用于功率转换器的控制器。所述功率转换器包括转换器开关和转换器电感器。所述控制器包括：控制器输出端，其被配置成提供用于转换器开关的开关控制信号；比较器；以及延迟块。所述比较器可以提供比较器输出信号，所述比较器输出信号取决于感测信号是否大于参考信号而具有比较器输出状态，其中所述比较器输出状态可以为第状态值或第二状态值。所述延迟块可以进行以下操作：基于(i)跨越转换器电感器的电压设置时间延迟值；当比较器输出状态改变时开启计时器；以及当所述计时器达到所述时间延迟值时引起所述开关控制信号中的改变。
