“…Thanks to its high output quality, SVPWM is chosen preferentially in many PMSM drives [18]. The modulation ratio m (fundamental voltage amplitude to carrier amplitude) of SVPWM can reach 1.15 in the absence of overmodulation [19] [20]. For the MFCS, the inverter's mean duty-cycle α h should be analyzed before using PWM technologies since the existence of the EDC.…”

The multi-functional converter system (MFCS) is a special topology of three-phase AC motor drives, which inherently integrates a DC-voltage regulation function. Firstly, in order to explain the mechanism of the MFCS, an average model is derived. An equivalent circuit is developed, which explicitly reveals that the MFCS is equivalent to a cascaded DC/DC converter-DC motor drive system. Secondly, the inverter's mean duty-cycle is identified as an independent control degree of freedom for the DC-bus voltage. Then, the influence of pulse width modulation (PWM) on the DC-bus voltage is studied. It concludes that space vector PWM is invalid for the MFCS. To address this problem, the zero-sequence voltage injection PWM (ZSVIPWM) is proposed and actually sinusoidal PWM is a special case of the ZSVIPWM. Thirdly, an overall control strategy is proposed for the MFCS, which includes not only the vector control for the motor but also a closedloop control for the DC-bus voltage. Finally, comparative experiments with the standard topology are carried out on a permanent magnet synchronous machine prototype to verify these theoretical analyses and the control strategy.

“…The switching of ZSIs can be done by space vector [8–14] and carrier‐based sine wave modulation methods. Several carrier‐based pulse‐width modulation (PWM) techniques such as simple boost control (SBC) [1], maximum boost control (MBC) [15], and maximum constant boost control (MCBC) [16] techniques are suggested to produce the ST state.…”

This study proposes a new pulse‐width modulation (PWM) technique for impedance source inverters, namely non‐tangential maximum boost control (NTMBC) technique at which the voltage gain of inverter in high‐modulation indices is higher than those of three traditional carrier‐based sine wave PWM techniques (simple boost control, maximum boost control (MBC), maximum constant boost control). In the conventional MBC technique, the duration of shoot‐through (ST) states varies from one switching cycle to another. This drawback results in a greater low‐frequency output frequency‐dependent ripple on both inductor current and voltage of the capacitor. Using the proposed NTMBC the ST duty cycle ratio can be kept approximately constant at each switching cycle. Consequently, in comparison with MBC, the peak value of inductor current, as well as its ripple, is noticeably low in the proposed NTMBC. Additionally, the source and ST currents in the proposed NTMBC method are less than those in the conventional MBC method. Using the proposed ST states does not have a considerable effect on total harmonic distortion (THD) of output waveforms and the THD in the NTMBC method is in a reasonable range. The proposed NTMBC method is validated using an experimental set‐up.
