A new three-level indirect matrix converter with reduced number of switches
Presentation / Conference Contribution
Klumpner, C., Lee, M. Y., Pitic, C., Wheeler, P., & Zanchetta, P. A new three-level indirect matrix converter with reduced number of switches. Presented at IEEE-IAS 2007 Annual Meeting

Matrix converters are sine wave in/out forced commutated single-stage AC/AC direct frequency changers using a single bi-directional switch to connect any input to any output. Indirect two-stage matrix converters provide similar input and output perfo... Read More about A new three-level indirect matrix converter with reduced number of switches.

A more efficient current source inverter with series connected AC capacitors for photovoltaic and fuel cell applications
Presentation / Conference Contribution
Klumpner, C., Chonlatee, P., & Wheeler, P. (in press). A more efficient current source inverter with series connected AC capacitors for photovoltaic and fuel cell applications.

Renewable energy sources such as photovoltaics (PVs) or fuel cells (FCs) are not fitted for direct power grid connection because they deliver DC voltage and current. In addition, they also have a high internal resistance/nonlinear V/I dependence, whi...
