Load driver and control method for safely driving DC load and computer-readable recording medium with program recorded thereon for allowing computer to execute the control |
摘要 |
In regenerative braking mode, an inverter converts, according to PWMC signal from a control unit, an AC voltage generated by a motor into a DC voltage to supply the converted DC voltage to an up-converter which down-converts the DC voltage to charge a DC power supply. The control unit receives voltage V 2 from a voltage sensor to stop the up-converter if voltage V 2 is higher than a predetermined value. The control unit further receives voltage Vf from a voltage sensor that is applied to a DC/DC converter and stops the up-converter if voltage Vf is higher than a predetermined value. Moreover, the control unit receives voltage V 1 of the DC power supply from a voltage sensor to stop the up-converter if voltage V 1 does not match voltage V 2.
