Average-current-mode control employs two loop control methods, an inner loop for current and an outer one for voltage. The proposed buck converter using the current-sensing and average-current-mode control tech
1. PCM-controlled buck converter. To achieve an accurate current control, average current mode (ACM) control is widely used in power converters. Many com- mercial IC adopt ACM control for different applications, includ- ing the multiphase voltage regulator (VR) [3], [4], point-of-load ...
Figure 1. Functional block diagram of a buck converter operated in ACMC. In the diagram, CEA = current-error amplifier, CSA = current-sense amplifier, VEA = voltage-error amplifier. The inductor current signal, iL, is discussed below and in Figure 2. To better understand ACMC...

This paper presents a duty cycle generator for an average model of buck converter with current-mode control, which can simultaneously deal with both the continuous conduction mode (CCM) and the discontinuous conduction mode (DCM). First, a duty cycle generator is mathematically derived, considering...
