A novel 36-step voltage source converter, that allow the number of steps in the output voltage to be increased is proposed. The operational feasibility of the 36-step converter is verified using computer simulations performed with the PSCAD/EMTDC programs and experimental studies performed on a 2 kVA hardware prototype. The propsed 36-step back-to-back converter is shown to be able to indpendently control the active and reactive power of HVDC systems.
