| Abstract |
A new multiple DC-inputs direct electric-power converter (D-EPC) has been developed. It is placed between multiple dc power sources and an AC motor, eliminating the need for a DC/DC converter generally used in conventional
converter/inverter systems. D-PEC can improve the efficiency of the motor drive system with a more compact size. Its
power distribution control is carried out by allotting voltage ratios to each of two different DC power sources on a time
average basis. A new pulse width modulation (PWM) generation technique to drive switching devices in D-EPC has also been developed. Tests have verified that the three-phase AC motor can be operated by controlling the power distribution between the two power sources. |
