The rapid growth of AI applications in data centers has led to a surge in the development of new hardware accelerators, resulting in increased power demands and energy consumption. To mitigate this trend, it is essential to focus on enhancing efficiency, particularly in the power conversion chain. Inefficiencies in this chain lead to heat generation, necessitating cooling systems that consume additional energy resources. This creates a vicious cycle, where increased power consumption leads to greater heat generation, which in turn requires more energy to cool. This digest introduces a compact ultra-low profile Current Multiplier module, exploiting the advantages offered by the Hybrid Switched Capacitor (HSC) topology. Experimental results show the effectiveness of the topology achieving high current density of 1.1 A/mm^2.
