Abstract :
The present work deals with the development and control of a converter to drive piezoelectric actuators. Due to the piezoelectric load specification, a half-bridge converter is proposed. Such a converter is analyzed considering charging and discharging modes. The converter is controlled by means of a sliding mode control strategy, employing two different sliding surfaces for the charging and discharging operation mode. The proposed scheme is validated by means of simulations.
