This paper describes influence real semiconductor devices, commutation strategies, modulation period selection and switch on resp. switch off times on output voltage of matrix converter. Methods for decreasing of the influence are mentioned in the paper too.
The matrix converter is a very popular topic because of its advantages in comparison with the indirect frequency converter. Output voltage is produced by the direct switching of output phases to input phases. The modulation strategy and control algorithm used are very important parts of the converter's controller. Common modulation strategies from the field of indirect frequency converters cannot...
A concept for the integration of intermitted trench gates into silicon lateral double-diffused metal–oxide–semiconductor (LDMOS) devices is proposed to achieve a significant reduction in on-resistance. The trench structure can be feasibly integrated into smart-power integrated circuit technology. Using 2-D technology computer aided design (TCAD) simulations, the achievable reduction in ...
Piezoelectric transformers (PTs) reveal a promising potential to replace conventional transformers in driving circuits for switching power applications, e.g. high-side driver for IGBT or MOSFET switches. With the realized driver design it is possible to transfer - galvanically insulated - both energy and information with one single PT. Above all, adapted with resonant driver topologies PTs offer increased...
