Abstract:
(EN) Disclosed are a voltage conversion circuit and method, and a multi-phase parallel power supply system. A feedback circuit provides a frequency-controllable feedback ripple signal, so that the working frequency of the voltage conversion circuit can be controlled, so as to meet the requirement of a load on a frequency. Moreover, a lag mode does not require compensation, and a response speed is high. Moreover, since the working frequency is fixed, the voltage conversion circuit can be applied to the multi-phase parallel power supply system, so that the multi-phase parallel power supply system can satisfy a heavy-load current application scenario.
(FR) L'invention concerne un circuit et un procédé de conversion de tension, et un système d'alimentation parallèle polyphasée. Un circuit de rétroaction fournit un signal d'ondulation de rétroaction commandable en fréquence, de manière à pouvoir réguler la fréquence de fonctionnement du circuit de conversion de tension pour satisfaire l'exigence d'une charge en termes de fréquence. De plus, un mode de retard ne nécessite pas de compensation, et une vitesse de réponse est élevée. De plus, étant donné que la fréquence de fonctionnement est fixe, le circuit de conversion de tension peut être appliqué au système d'alimentation parallèle polyphasée, de manière que le système d'alimentation parallèle polyphasée puisse satisfaire un scénario d'application de fort courant de charge.
(ZH) 一种电压转换电路、方法和多相并联电源系统,通过反馈电路提供频率可控的反馈纹波信号,使得电压转换电路工作频率可控,满足负载对频率需求,并且迟滞模式无需补偿响应速度快。同时由于工作频率固定,可以将电压转换电路应用于多相并联电源系统中,使其满足大负载电流的应用场景。
