Abstract :
This paper proposes the development of a high-performance push-pull DC-DC converter model with multiple stages whose inputs are connected in parallel to the 12 VDC supply voltage and outputs in parallel to the secondary winding of each converter. This configuration allows to mitigate the current efforts as much in the inputs as in the outputs of each conversion stage, in order to characterize a multiconverter with 220 VDC and 4.4 kW in output intended to a purely resistive load.
