Abstract: A power converter using constant on-time (COT) or ramp pulse modulation (RPM) control achieves more rapid resumption of steady-state operation after a step-up load transient by extending an on-time of a switching pulse by interrupting a ramp voltage waveform that is compared with a threshold that equals a threshold voltage at the termination of a switching pulse or increasing a voltage with which the ramp voltage is compared. These techniques are applied to both single-phase and multi-phase power converters.

Abstract translation: 使用恒定导通时间（COT）或斜坡脉冲调制（RPM）控制的功率转换器通过通过中断斜坡电压来延长开关脉冲的导通时间来实现升压负载瞬变之后的更快恢复稳态操作 该波形与等于开关脉冲终止时的阈值电压的阈值进行比较，或增加与斜坡电压进行比较的电压。 这些技术适用于单相和多相功率转换器。
