Self oscillating gate control vs PLL for resonant frequency: marko . . . The self oscillating switching naturally and quickly follows the resonant frequency and handles changes to that frequency well The gate signal is also pretty clean, compared to what I've seen with the "marko zvs" circuit
Comparison of Different PLL Implementations for Frequency Estimation . . . To this aim, the paper compares five well-assessed PLL implementations through a standard IEEE benchmark system considering both contingencies and noise Keywords—Distributed energy resources, frequency control, frequency estimation, frequency-locked loop, phase-locked loop
Novel phase-locked loop-based resonant frequency tracking control for . . . The paper presents a novel phase-locked loop (PLL)-based resonant frequency tracking method for linear compressors with oscillatory motions The proposed method achieves the phase-locked control between two signals by using PLL, which includes a multiplier, and a low-pass filter to obtain the phase signal difference
High Efficiency Synchronous Rectifier using Phase Locked Loops DTU . . . Instead the Phase Locked Loop (PLL) and Delay Locked Loop (DLL) was identified as interesting circuit elements to achieve synchronous rectification Both the PLL and DLL can be used to synchronize the phases of two signals efficiently
Design of self-oscillating resonant converters based on a variable . . . Self-oscillating control of resonant converters is becoming increasingly popular among designers because it allows a much closer operation to the resonant frequency than conventional forced-frequency control while preserving zero-voltage switching
Self oscillating gate control vs PLL for resonant frequency: marko . . . Self oscillating gate control vs PLL for resonant frequency: marko, royer, ZVS, mazzilli, etc flyrod, Wed Jan 10 2018, 02:14PM I've been looking for a simple way to clean up the gate signal of a royer zvs circuit and I came across this paper: It describes a way to switch the gates without the complexity and problems of a PLL approach
Oscillator Design… 1 Power range and application. Sine vs . . . - NASA Oscillator is a single-transistor self-resonant Hartley-Armstrong derivative using a resonant secondary Develops a harmonically pure sine wave output and is essentially immune to radiation and temperature induced gain reduction in the drive circuit
