一种无需电流传感器的DC-DC升压变换器输出电容ESR在线估计方法

Aluminum electrolytic capacitors (AEC) as a high energy density, low-cost energy storage component, are widely used in power electronic converters to stabilize the output voltage. However, the AEC is reported as a vulnerable component, threatening the reliability of power electronic converters. The health status of AEC is reflected in the variation of its equivalent series resistance (ESR). Theref...
