Passivity Checking and Enforcement

A passive system does not contain any energy sources. Frequency-dependent data may nevertheless exhibit non-passive behavior. SIwave offers four methods for passivity checking and enforcement: an iterated fitting method, an iterated fitting method for better Z-fit at DC and low frequencies, a convex programming method, and a perturbation method.

• Convex Programming Method
• Perturbation Method
• Iterated Fitting of Passivity Violations (IFPV) Algorithm
• Iterated Fitting of Passivity Violations Low Frequency (IFPVLF) Algorithm
