An Impedance-Based Digital Synchronous Rectifier Driving Scheme for Bidirectional High-Voltage SiC LLC Converter

IEEE transactions on industrial electronics (1982. Print), 2022
Conventional digital LLC synchronous rectifier (SR) control typically uses detection circuits to sense the drain-source voltage of SR MOSFET in low output voltage applications, or gives SR duty cycle only considering the switching frequency in the ...

A Novel Synchronous Rectifier Driving Scheme for LLC Converter Based on Secondary Rectification Current Emulation

IEEE transactions on power electronics, 2022
In conventional synchronous rectifier (SR) driving schemes, the drain to source voltage of SR is detected to generate its driving signal. However, the driving signal by this method will lose a portion of duty cycle due to the parasitic inductance in SR ...

A Sensorless Model-Based Digital Driving Scheme for Synchronous Rectification in 1-kV Input 1-MHz GaN LLC Converters

IEEE transactions on power electronics, 2021
For 1-MHz GaN LLC converters with 1-kV input, the switching speed of eGaN high-electron mobility transistors (HEMTs) is as fast as 6 ns, which results in dv/dt up to 200 kV/μs. It poses serious challenge for synchronous rectification (SR).
