Study of Chaos in Voltage Controlled DC-DC Buck Converter
Power electronics as an application oriented discipline, has been employed in industrial, commercial, residential and aerospace environments. Since power electronic circuits containing pulse width modulation, are nonlinear systems, it exhibits complex behaviors such as bifurcation and chaos. In this paper, a simulation study of chaos in voltage controlled buck converter is done by varying the l...
متن کاملResonant Parametric Perturbation Method to Control Chaos in Current Mode Controlled DC-DC Buck-Boost Converter
Abstract – Resonant parametric perturbation (RPP) method is an effective non-feedback method for controlling chaos. In this paper, the above method is applied for the current programmed buck-boost dc-dc converter which exhibits chaotic for wide parameter variations. The different possible operating regimes leading to chaotic operation of the current mode controlled buck-boost converter is discu...
متن کاملReducing Electromagnetic Interference in DC-DC Converters with Chaos Control
Electromagnetic Interference (EMI) resulting from high rates of changes of voltage and current, impairing other devices’ performance and harming human being’s health, has become a major concern in designing direct current (DC-DC) converters for a long time due to the increasingly wide applications of various electrical and electronic devices in industry and daily life. Thus, the question of how...
متن کاملApplying Resonant Parametric Perturbation to Control Chaos in the buck DC/DC converter with Phase Shift and Frequency mismatch Considerations
The buck converter has been known to exhibit chaotic behavior in a wide parameter range. In this paper, the resonant parametric perturbation method is applied to control chaos in a voltage-mode controlled buck converter. In particular, the effects of phase shift and frequency mismatch in the perturbing signal are studied. It is shown that the control power can be significantly reduced if the pe...
متن کاملPeriodic Perturbation Method for Controlling Chaos for a Positive Output DC-DC Luo Converter
Received Jan 5, 2017 Revised Mar 5, 2017 Accepted Mar 19, 2017 A simple, non-feedback method of controlling chaos is implemented for a DC-DC converter. The weak periodic perturbation (WPP) is the control technique applied to stabilize an unstable orbit in a current-mode controlled Positive Output Luo (POL) DC-DC converter operating in a chaotic regime. With WPP, the operation of the converter i...
