Application of $$I^{2}$$ I 2 technique on dual current mode control of power electronics converters

Abstract

One of the main objectives of the latest advanced current mode control (CMC) methods for power electronics converters is eliminating error between the average value of the inductor current and the reference current over each switching period, in steady and transient state. A special attention is devoted to the $$I^{2}$$ average current mode control ( $$I^{2}$$ ACMC) method, which ensures both accurate current tracking and fast dynamic response. A new application of the $$I^{2}$$ concept on dual current mode control (DCMC) method is introduced in this paper. A detailed analysis of the proposed $$I^{2}$$ DCMC is performed for two-quadrant (2Q) buck converter, but it can be extended to any type of converter. The obtained simulation and experimental results confirm the performed analysis and demonstrate excellent features of the proposed $$I^{2}$$ DCMC method.
