Abstract
An onboard powertrain for an automated guided vehicle, AGV, is presented herein. The onboard powertrain includes a split-source inverter, SSI, having at least one middle point pole, a positive DC-link pole, and a negative DC-link pole, a battery and an inductor connected in series between the positive or negative DC-link pole and the middle point pole, and a supercapacitor connected between the positive and negative DC-link poles.
Claims20
An onboard powertrain for an automated guided vehicle, AGV, the onboard powertrain comprising:
- a split-source inverter, SSI, having at least one middle point pole, a positive DC-link pole, and a negative DC-link pole;
- a battery and an inductor connected in series between the positive or negative DC-link pole and the middle point pole;
- and
- a supercapacitor per electrical phase (Vs, Vb, Vc) of the SSI, each connected between a common negative DC-link pole for the SSI and a separate positive DC-link pole per phase of the SSI.
An onboard powertrain for an automated guided vehicle, AGV, the onboard powertrain comprising:
- a split-source inverter, SSI, having at least one middle point pole, a positive DC-link pole, and a negative DC-link pole;
- a battery and an inductor connected in series between the positive or negative DC-link pole and the middle point pole;
- a supercapacitor connected between the positive and negative DC-link poles;
- and
- an off-board charger with a step-down transformer.
