Single-Phase Simplified Split-Source Inverter (S3I) for Boost DC–AC Power Conversion [PDF]
IEEE Transactions on Industrial Electronics, 2019 The single-phase split-source inverter (SSI) is an emerging and attractive topology for a boost dc–ac power conversion system. Such as an inverter features high compactness, although at the expense of high-frequency commutations across the diodes. The corresponding hybrid pulsewidth modulation (PWM) also confines the voltage harmonics to concentrate ...
