摘要

<正>B. Virtual Inverter Control) As shown in Fig. 3, the virtual inverter controller is similar to the conventional one. Note that the controller has a dc-link voltage compensation because the virtual dc-link voltage contains the ripple component, as explained above. The dc-link voltage is obtained by the relation between the instantaneous power of the ac and dc sides. The dc-link voltage can be expressed as
