Abstract:

This paper describes an optimized SPWM modulation technique with new topology for doubling the frequency and current while minimizing hardware costs.Double output current is achieved without the need for increasing the frequency of the switch and complex hardware in the output voltage multiplier.Matlab/Simulink simulation of an asmodulated inverter is performed to verify the feasibility of the proposed modulation technique and topology.Practical application also demonstrates good equalization effect and low MOSFET temperature and thus frequency is doubled and capacity is enlarged.

Key words: inverter;new modulation technology;double frequency and current;new topology
