Abstract
This contribution introduces a design procedure for Double Integral Sliding Mode Control (DISMC) applied on buck converter derived topologies. The Voltage Mode Control (VMC) based control strategy is expanded by a deadzone compensated current control to stabilize failure conditions such as short-circuits. A control concept for distributed converters is derived and verified by means of test-bench based measurements. DISMC is validated on a prototyped 1 kW converter and compared to industry standard PI based control designs. Both settling time and overshoot amplitudes can be reduced by up to 67% and 35%, respectively.
