Abstract

A ripple correlation control (RCC) algorithm with capacitive compensation is introduced for photovoltaic applications. In principle, RCC convergence times and steady-state error are reduced with higher switching frequencies, but circuit parasitics have typically limited RCC operation to tens of kHz. With capacitive compensation, phase information is retained at higher frequencies and the practical switching range is extended to 100 kHz. Simulations show that even approximate estimates of parasitic capacitance, with margins of error as high as 20% or so, can greatly extend RCC operating frequency. A 100 kHz boost prototype is constructed and used to verify that phase information is recovered with capacitive compensation.
