title = "An energy-saving scheme of motor drive systems based on ultracapacitors",
abstract = "In order to prevent DC link voltage pump during braking, a paralleled release circuit composed of chopper and resistor is often employed. As a result of energy waste on the resistor, the efficiency of the motor drive system is low in the case of frequent braking. To improve the efficiency, an energy-saving scheme of motor drive systems based on ultracapacitors is proposed in this paper. An energy storage system (ESS) paralleled with the DC link of the motor drive is adopted in the scheme, which is composed of a bidirectional DC-DC converter and ultracapacitors. The ESS can realize recycling of the braking energy. Compared with PWM rectifier, this scheme can avoid various technical requirements for grid-connected inverters.",
