ʻO ka GDQ54S12B-4PD kahi hanauna hou i hoʻokaʻawale ʻia DC-DC converter e hoʻohana ana i kahi ʻano hana quarter-brick maʻamau, e hōʻike ana i ka ffin kiʻekiʻe a me ka mana mana me ka ripple haʻahaʻa a me ka walaʻau. Hoʻohana ia mai kahi kikowaena voltage input o 36V a i 75V, a hāʻawi i ka volta puka helu helu o 12V a me ka nui o ka hopena o kēia manawa o 54A.
