4. ABSTRACT
A boost-voltage motor driver with a charge pump (CP) circuit has higher efficiency than
the conventional boost-voltage motor driver with a chopper circuit. This paper presents a variable-
form carrier-based (VFCB) pulsewidth modulation (PWM) technique for the driver with the CP circuit.
This technique has two triangular carriers and a variable-form carrier that is dependent on the
voltage command signals. The technique is compared with the space vector modulation (SVM)
technique in terms of the number of switching cycles, harmonics in the output voltage, linear
modulation range, input power to the CP capacitor, processing time, and efficiency. The VFCB PWM
technique is confirmed to operate the driver with the CP circuit at the same performance level as
the SVM technique, with shortened processing time.
