During the brake process of the converter powered ship propulsion system,the propulsion motor will feedback energy to the converter for the propeller characteristic,which would cause the converter burned because of over-voltage.

Development of the energy feedback device on the control system of gantry planer;

Study on energy feedback equipment based on high-frequency PWM rectifier/inverter;

A general inverter energy feedback control system based on SA4828;

Research of the energy feed back problem of frequency converters on oil pumping units;

Electric bicycle with energy feed back by the use of DSP and permanent magnet synchronous motor (PMSM) has good foreground because of its energy-saving and high energy efficiency.

According to the special requires of bridge crane, it adopts the vector control theory, has functions of regulating speed smoothly, energy feed back, sequence brake etc.

A test-bed for electric propulsion with twin inverter-motor reciprocal power-fed is constructed in order to investigate the technology of marine electric propulsion.

A novel Twin Inverter-Motor reciprocal power-fed AC drive experiment system is introduced in this paper.

Based on the dynamic mathematical model of linear induction motor (LIM),a novel reciprocal power-fed linear drive experiment system was researched.

It has the function of auto maintenance time discharge with energy fed infinite bus.

In this paper the author discussed a kind of solution and method of energy feedback type electronic load used in aero-dynamo testing.
