Auto-Compensation Method for A Buck Converter
Journal Title: Acta Technica Napocensis- Electronica-Telecomunicatii (Electronics and Telecommunications) - Year 2012, Vol 53, Issue 2
Abstract
The paper proposes a method to compute the passive components values of a synchronous buck converter. The method is implemented on a step down converter using a DSC(digital signal controller) F28027 from Texas Instruments. A third order IIR filter is used for compensation and the coefficients are computed automatically based on the components determined values. The algorithms for computing the inductance, capacitance and capacitor parasitic resistance are presented in detail with flow charts and simulations. The software is then transposed in code composer and the algorithm is tested on the experimental setup. The algorithm once implemented doesn’t need recalibration of the compensator coefficients made by an operator in case of a hardware change in the power circuit.

In this paper we present a global no-reference blur metric based on a local approach of blur detection in natural macro-like images. The purpose is to study the possibility of global assessment based on thedetection of b...
Broadband Power Amplifier Nonlinearity Cancellation in OFDM Systems
One drawback of OFDM systems is the high peak-to-average power ratio, which imposes strong requirements on the linearity of power amplifiers (PAs). Such linearity requirements translate into high back-off that results in...
