Resonance helps boost power efficiency
One of the biggest contributions to the surge in efficiency has been the adoption of architectures that make use of resonance. Reducing current or voltage to zero, or as close as possible, before activating or deactivating the power path, reduces the losses of hard switching. Since its development in the 1980s, the main way of implementing this
