In order to do so, the interconnection of classical topologies or the optimized design of new ones is being prospected. This approach usually leads to a higher complexity in the power control strategies. Thus, multiplexed load power control is used due to its versatility with the different topologies. Despite the advantages of this technique, power variations over the different pots generate a change in the forces between those and the inductors that might generate acoustic noise. This paper analyses multiplexed load power control and its restrictions and presents a modulation strategy based on switching frequency and duty cycle variation that allows a soft-transient load activation and deactivation, reducing the generated acoustic noise.2020http://zaguan.unizar.es/record/12810510.3233/JAE-209115http://zaguan.unizar.es/record/128105oai:zaguan.unizar.es:128105International journal of applied electromagnetics and mechanics 63, S1 (2020), S59-S68All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
