| Abstract: | To feedback the regenerative energy of braking timely and effectively, a novel energy-feedback control system based on 3-phase pulse width modulation engine SA4828 was developed.The system configuration and operation principle were discussed at first,then the design method of energy-feedback microprocessor supervisory system was given.The resolution of control and display were improved by adding a subtraction circuit in detection of DC voltage.A 15kVA prototype is built in laboratory,the experimental results show that the system design reasonable with more than 30% of energy-saving effect,which extent the application of general inverter.By the use of SA4828,the system has the merits of simple configuration and low feedback current harmonic,which give it a good application prospect. |
