A fixed-frequency hybrid modulation method for single-phase full-bridge inverters based on the RACL topology is proposed in [13]. In addition, soft-switching technology has also been applied to existing

Omitting direct control methods such as Direct Torque Control (DTC), the phase voltages are mostly generated through a pulse-width-modulation (PWM) technique. Two of the most well-known

Pulse width modulation in voltage source inverters with an arbitrary number of phases is analyzed in this paper. The problem is treated as purely algebraic, without any use of space vectors.

The proposed amplitude modulated triangular carrier PWM (AMTCPWM) method increases linear range of the SPWM, avoids the pulse dropping region and reaches to the square wave boundary. The

In this paper, a novel method based on space vector pulse width modulation (SVPWM) for a five-phase voltage source inverter is presented, which uses a proposed sampling time sharing

The maximum modulation index is defined here as the ratio between output phase-to-neutral voltage (peak) of the fundamental component and the DC-link voltage except for when the inverter is over
