Continuation method in multitone harmonic balance

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
Design of communication circuits often requires computing quasi-periodic steady state response to multiple inputs of different frequencies that may not always be harmonically related. Multitone harmonic balance method can be used to provide an accurate solution if the circuit is mildly nonlinear.

The Method of Harmonic Balance

2011
This method may be used to determine the approximate periodic solutions of nonlinear differential equations. If a periodic solution does exist, it may be sought in the form of a Fourier series, whose coefficients are determined by requiring the series to satisfy the equation of motion.

A new development of the harmonic balance method: The hybrid harmonic balance method

Analysis and Applications
The harmonic balance (HB) method is efficient in predicting the limit cycle oscillations for many dynamic systems including very high dimensional systems in fluid dynamics. Recently, some variations and extensions of the HB method have been developed and employed in the computation of large systems.

A generalized harmonic balance method for EMTP initialization

IEEE Transactions on Power Delivery, 1995
The harmonic balance method is extended to the steady-state analysis of power system models that include complex nonlinearities and variable topology power electronics equipment as may be user-assembled from basic EMTP-TACS components. In applying the harmonic balance method, these devices are considered as black boxes and isolated from the linear part

A filter-based technique for the harmonic balance method

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1996
The Harmonic Balance Method (HBM) allows an efficient determination of the steady-state solution of mildly non-linear circuits; however, in the presence of strong nonlinearities, it often fails to converge. The reasons of such behavior are investigated in this paper. In order to improve convergence, a modified HEM technique is presented, based upon the

Solution of a Duffing-harmonic oscillator by the method of harmonic balance

Journal of Sound and Vibration, 2006
Abstract The first-order harmonic balance method via first Fourier coefficient is used to construct an approximate frequency–amplitude relation for a Duffing-harmonic oscillator. This relation is in agreement with the result obtained by the Ritz procedure.

A generalization of the method of harmonic balance

Journal of Sound and Vibration, 1986
A procedure is provided for generalizing the method of harmonic balance to obtain higher-order approximations to the periodic solutions of differential equations for two systems, one a conservative system and the other nonconservative. The procedure is currently being applied to investigate the possible solution behaviors of singular, nonlinear ...

Convergence analysis for the harmonic balance method

Nonlinear Analysis: Theory, Methods & Applications, 1993
The paper deals with the convergence analysis of the harmonic balance method appearing in nonlinear circuit analysis where the circuit splits into linear and nonlinear subcircuits. The linear convolution operator is evaluated in frequency and the nonlinear substitution operator in time.

Extended harmonic balance method

IEE Proceedings - Circuits, Devices and Systems, 1994
A new approach for frequency domain analysis and periodic steady state analysis of nonlinear circuits is described. Beside the variables generally used in the harmonic balance method (HBM) this method also uses a reduced waveform as a function of time.
