A cost-effective solution to power the gate drivers of multilevel inverters using the bootstrap power supply technique [PDF]

open access: yes, 2009
Multilevel inverters are traditionally seen as a step forward in DC/AC conversion, providing more output voltage levels, better quality of the generated waveform and lower switching losses than the two-level and can process higher voltages with a given ...

Frequency reduction schemes for back-to-back connected, diode-clamped multilevel converters

open access: yesIET Power Electronics, 2010
Two new switching schemes for back-to-back connected diode-clamped multilevel converters that reduce the devices switching frequency while maintaining capacitor balancing are presented. Comparisons are made between a previously reported ‘optimal’ balancing strategy and the two proposed switching techniques using data gathered from a prototype five ...
