针对采用峰值电流模式控制(PCMC)的Boost变流器，提出了一种精确计算其开环传递特性的建模方法。基于PCMC的Boost转换器的建模有很多技术；然而，所有这些技术都专注于纯阻性负载，对于纯电容负载并不总是准确的。本文提出了一种新的建模方法，该方法简单，对电容负载和阻性负载都能给出准确的结果。此外，还推导出了采用PCMC的Boost转换器在连续导通模式下的直流增益和极点位置的实用表达式，并与仿真和测量结果进行了比较。
A modeling approach is presented that calculates an accurate open-loop transfer characteristic for a boost converter that employ peak current-mode control (PCMC). Many techniques exist for modeling a PCMC-based boost converter; however, all these techniques focus on purely resistive loads and are not always accurate for a purely capacitive load. In this paper, a new modeling technique is presented, which is simple and gives accurate results for both capacitive and resistive loads. Furthermore, the useful expressions for dc gain and pole locations of a boost converter operating in continuous-conduction mode with PCMC are derived and compare well to simulations and measurements.
