峰值电流模式控制三电平飞跨电容变换器的无传感器稳定技术

This article describes a sensorless stabilization technique for peak current mode control of three-level flying-capacitor (3LFC) buck converters. The technique eliminates the well-known instability associated with the flying-capacitor (FC) voltage runaway, leading to stable and balanced FC voltage. In the proposed technique, the FC voltage imbalance is detected by measuring the duty cycle mismatch...
