Improving adaptive resolution of analog to digital converters using least squares mean method

This paper presents an adaptive digital resolution improvement method for extrapolating and recursive analog-to-digital converters (ADCs). The presented adaptively enhanced ADC (AE-ADC) digitally estimates the digital equivalent of the input signal by utilizing an adaptive digital filter (ADF). The least mean squares (LMS) algorithm also determines the coefficients of the ADF block. In this sch...

Time-shift Control of LLC Resonant Converters

This paper describes a new control technique for resonant converters that outperforms the direct frequency control (DFC) method implemented in all today’s commercially available control ICs. When applied to LLC resonant converters, the resulting dynamic behavior is that of a low-Q second-order system or that of a first-order system, depending on the operating conditions. Thus closing the contro...

On Model Predictive Control of Quasi-Resonant converters

In this paper, different model predictive control synthesis frameworks are examined for DC–DC quasi-resonant converters in order to achieve stability and desired performance. The performances of model predictive control strategies which make use of different forms of linearized models are compared. These linear models are ranging from a simple fixed model, linearized about a reference steady st...

Soft Switched Resonant Converters with Unsymmetrical Control

Using PSPICE a resonant dc-dc converters operating at constant frequency was simulated. The paper concentrates on the working of a half bridge topology employing ZVS techniques. The operation of converter with LC filter in the output is discussed. The design and fabrication was done on a 5V, 50W converter using MOSFET to validate the performance of the converter. The converter has illustrated l...

DC-DC Resonant converters with APWM control

An asymmetrical pulse width modulated (APWM) dc-dc converters operating at constant frequency was simulated using Pspice software package. This converter incorporates constant frequency operation in a basic soft switching half bridge topology without any additional component and complexity. In this paper operation of converter configuration with capacitive filter in the output is discussed. A 5...
