Abstract
A power system includes a traction battery, and a rectifier including a pair of diodes, a pair of switches, and a pair of capacitors each in parallel with a different one of the switches such that alternating current input to the rectifier results in alternating voltage having parabolic approaches to maximum magnitude values being input to the rectifier. The maximum magnitude values correspond to a magnitude of voltage output to the traction battery.
Claims18
A power system comprising:
- a traction battery;
- and
- a rectifier including a pair of diodes, a pair of switches, and a pair of capacitors each in parallel with a different one of the switches such that alternating current input to the rectifier results in alternating voltage having parabolic approaches to maximum magnitude values being input to the rectifier, the maximum magnitude values corresponding to a magnitude of voltage output to the traction battery.
Vehicle power system circuitry comprising:
- a rectifier including a pair of diodes, a pair of switches, and a pair of capacitors each in parallel with a different one of the switches such that alternating current input to the rectifier and complementary operation of the switches results in alternating voltage having zero-dwell periods immediately followed by parabolic approaches to maximum magnitude values being input to the rectifier.
A vehicle power inverter comprising:
- a rectifier including a pair of diodes, a pair of switches, a pair of capacitors each in parallel with a different one of the switches, and another capacitor in parallel with the pair of capacitors, the pair of switches being electrically between the pair of diodes and the pair of capacitors, and the pair of capacitors being electrically between the pair of switches and the another capacitor.
