Abstract:
This paper details the design of a digitally controlled isolated
SMPC containing a novel bi-directional data transmission scheme The
bi-directional data transmission scheme avoids the effects of opto-coupler
aging, allows the use of digital control techniques and enables transmission of
auxiliary data from primary-to-secondary and secondary-to primary. The complete
digital controller was implemented on one custom and two FPGA boards.
An efficient high-speed bi-directional data transmission scheme for isolated AC-DC and DC-DC switched mode power converters is presented. The bi-directional scheme supports fast, efficient and reliable transmission of ...
This paper proposes a new FPGA-based architecture for a
multi-phase digital pulse width modulator (MP-DPWM). A novel
fine-leading/coarse-trailing edge modulation is applied to allow the sharing of
a single fine resolution ...

This paper considers the application of the discrete-time
structured singular value to assess the robustness of systems subject to real parametric
uncertainties. Since the associated uncertainty set is strictly real, ...
This paper proposes a state-dependent Analog-to-Digital Conversion
(ADC) scheme for digitally isolated Switched Mode Power Converters (SMPCs). The
SMPC voltage range is subdivided into three different regions corresponding ...

The design of a programmable voltage reference for a digital control dc-dc power converter is
presented. Propagation time errors on the analog pulse density modulated output signal lead to
Integral Non Linearity (INL) ...
