Dynamic physical limits of buck converters: The T<inf>0</inf>/4 transient benchmark rule

Dynamic physical limits of a phase-shifted full bridge circuit for power supply of Magnetic Resonance Imaging gradient amplifiers

“…Refer to [14], this paper presents a method to analyze the dynamic physical limits of the response to a sudden load current change of a PSFB converter that is designed for the power supply of MRI gradient amplifiers. The voltage undershoot and recovery time are calculated and the relationships between the dynamic physical limits and the circuit specifications are discussed.…”

“…To find a benchmark for estimating the dynamic performance, the dynamic physical limits of the Buck converter are presented in [14] where the limits of the dynamic performance depend on the LC filter specifications, the input and output voltages and the switching frequency.…”

Comparison of the behavior of voltage mode, V² and V²I<inf>c</inf> control of a buck converter for a very fast and robust dynamic response

“…Novel digital controls should be compared to them or to the benchmark limits derived from the Natural Trajectories [4] that the Centric-based control uses.…”
