AI Technical Summary
Technical Problem
Existing power converter systems suffer from inefficiencies due to switching losses caused by parasitic elements, which dissipate energy rather than recover it, particularly at higher switching frequencies.
Method used
A circuit design that incorporates a switching converter, an energy harvesting circuit, and a voltage regulator to capture and store energy from parasitic impedances during switch transitions, using a rectifier and capacitor to convert and supply this energy to power other circuit components.
Benefits of technology
Improves overall power efficiency by recovering energy stored in parasitic elements, reducing losses and enhancing performance at higher switching frequencies.

Abstract
In one described example, a circuit includes a switching converter comprising a switch with a first current input, a second current input, and a control input, each of the first and second current inputs having an associated parasitic impedance. An energy harvesting circuit has a third input and a first output, the third input being coupled to each of the first and second current inputs. A voltage regulator has a fourth input and a second output, the fourth input being coupled to the first output or an input voltage terminal, and the second output being coupled to a voltage terminal of the circuit.
