A passenger transport system includes a three-phase drive motor, a control device and an inverter module having power semiconductor switches. The gate electrodes of the power semiconductor switches are driven directly by the control device. The inverter module is connected on the input side to a DC source and on the output side to the three-phase drive motor. Between the DC source and the inverter module there is a DC circuit, wherein drive signals that can be modulated on the DC circuit can be generated by the control device, and the inverter module has a demodulator, by which demodulator the drive signals can be converted into control voltages assigned to the individual gate electrodes of the power semiconductor switches.
