Optimization of switching losses of the Weinberg converter

International Journal of Power Electronics and Drive Systems (IJPEDS), 2023
DC-DC converters are widely used in hybrid power supply systems. A buffer source of electrical energy (most often a battery bank) and its charging and discharging devices are integral parts of such systems. In systems where the battery bank voltage is less than the DC-bus voltage and galvanic isolation is not required, the Weinberg converter is widely ...
