DC/DC resonant converters for galvanic isolation use a resonant circuit, typically consisting of inductors and capacitors, to efficiently transfer energy between the input and output. The circuit operates at a resonant frequency at which losses are minimized. The reduction of switching losses and EMI contributes to a higher overall efficiency of the converter. Compared to conventional PWM-based DC/DC converters, the design of a resonant converter is more complex as the resonance conditions must be precisely tuned. Resonant operation allows higher switching frequencies to be achieved, which leads to a reduction in the size and weight of passive components (such as transformers and filters). The resonant technology also ensures that the voltage and current peaks that occur in conventional switching processes are reduced, resulting in less stress on the components.
The DC/DC converter topologies are fundamental components in the conversion of electrical power.
