본문

A cascaded H-bridge multilevel inverter (CHMI) is one of the promising candidates for highvoltage direct current (HVDC) distribution

system. The huge number of inverter cells and switching devices, which consists CHMI, imply a great switching loss and it requires

increased cost and size of the cooling components. To reduce the huge switching loss, a pulse-width modulation (PWM) strategy is

proposed in this paper, which is composed of two different modulation methods. In addition, an additional cell rotation method is

proposed to evenly distribute power among inverter cells which allow shaping three-phase output currents with reduced switching

loss. The simulation results verify the validity of the proposed modulation scheme.
