| Abstract |
In most of the ac-dc-ac-converters for low voltage drives aluminium electrolythic capacitors are used for
the energy storage in the dc-link. The main design criteria for this type of capacitor is its ripple current
capability. In this paper a full investigation of the influence of converter parameters like modulation
strategy, grid and load angle, dc-link voltage etc. on the ripple curent is represented. The results are
used to minimize the size and the capacity of the dc-link capacitor of a PWM rectifier - dc voltage link -
PWM inverter configuration substancially. |
