In order to realize the lightweight design and low-carbon operation of multi-system locomotive. an active suppression method of DC voltage secondary pulsation of reusable energy storage system was proposed. Bidirectional DC/DC circuit was used to transfer the secondary power pulsation in the four-quadrant converter to the auxiliary LC branch to suppress the intermediate voltage pulsat... https://www.medicalwarehouses.shop/product-category/skin-care-tools/
