Online Capacitance Monitoring for DC/DC Boost Converters Based on Low-Sampling-Rate Approach

Aluminum electrolytic capacitor (Al-Cap) is widely used in dc/dc converters to suppress voltage ripple and store energy to stabilize the output voltage. However, Al-Cap is one of the most vulnerable parts in power electronic converters, and its capacitance ( C ) is an important parameter for indicat...
