Sinusoidal Pulse-width modulation, SPWM, is inverter-leg-based, logical-operation-based, and lesscomputational-intensive. In this brief, these simplifying features of SPWM are extended to the control of the 10-switch, 3-level inverter. The control strategy is based on the single triangular carrier SPWM perspective. Procedures and details of the sharing of four-common power switches by the 3 inverter legs are given. Classically, a 2-wing, 20-switch dual-output inverter, DOI, is configured; which topologically provides flexibility of independent operation of the constituting inverter wings at reduced component-count. This independent operation entails each of the inverter retaining full modulation index operational range (0 to unity) for the same or different frequencies of operation. Experimental demonstrations of the proposed SPWM scheme in the control of the 2-wing, 20-switch DOI are adequately presented.
