Furthermore, the boost-voltage motor driver offers an effective and highly responsive motor drive. These advantages allow boost-voltage motor drivers to be employed in various other applications. The most commonly used boost-voltage converter used in boost-voltage motor drivers is a chopper circuit with an inductor. Alternatively, a boost-voltage motor driver with the charge pump (CP) circuit has been proposed. These drivers can have output voltage with lower harmonics and operate in higher efficiencies, although they have a more complex circuit configuration than conventional drivers with a chopper circuit. In the Appendix, the driver with the CP circuit is compared with a conventional driver with a chopper circuit under the conditions employed in this study and is confirmed to perform at higher efficiencies.

Web : www.lemenizinfotech.com / www.ieeemaster.com Mail : projects@lemenizinfotech.com Proposed system: This paper proposes a variable-form carrier-based PWM (VFCB PWM) technique that can be applied to the driver with the CP circuit, instead of the SVM technique. The VFCB PWM technique uses two triangular carriers and a variable-form (VF) carrier, the waveform of which depends on the magnitude of the voltage command signals. The switching signals of the CP circuit are determined by comparing the voltage command signals with the triangular carriers. The signals of the inverter are determined by comparison with the VF carrier. Advantages: High efficiency. Increase in the control frequency. Applications: Electrical vehicles.
