Abstract :
Proposed in this paper are three different implementations for digital average current mode control for DC-DC converters operating in the continuous conduction mode. The advantages and disadvantages of each implementation are described. Design procedures for the both the voltage and current loops are described. Using a boost converter prototype, the dynamic performance of all three implementations has been evaluated and is presented here.
