Small-Signal Impedance Measurement of Power-Electronics-Based AC Power Systems Using Line-to-Line Current Injection (2009, unknown): “Since then, impedance techniques have been used for power supply design [2], [3], and a number of stability criteria have been proposed [5], [7], [8] that involve magnitude and phase of the impedance.”
Impedance-Based Stability Criterion for Grid-Connected Inverters (2011, methodology): “The technique is widely used in the design of switching-mode power supplies with input filters [8], as well as more complex dc distributed power systems [ 9 ].”
Small-Signal Methods for AC Distributed Power Systems–A Review (2009, methodology): “An important feature of DPS is the conditioning of power by switching converters for individual loads (as well as sources in many cases.) Active control of these converters and the resulting nonlinear dynamics create complex system interactions that can lead to various stability and power quality pr”
