相模块化三相六开关Buck-Boost Y型逆变器谐波注入技术的比较评估

Phase-modular buck–boost dc/ac inverters extend the voltage conversion range of conventional buck-type inverter topologies, and accordingly offer significant advantages for variable-speed motor drives powered from dc sources with wide-voltage-ranges like fuel cells or batteries. In this letter, two new modulation schemes are applied to the six-switch buck–boost Y-inverter (6YI) topology, with an a...
