Simple implementation of control gate signals for the interleaved LLC resonant converter for high current application

Autor:

Myung-Bok Kim

Resumen:

A novel method of the gate signal generation for the interleaved LLC converter is proposed, which is based on the relationship between the output signal of a toggle flipflop having the double period of the input clock signal and the output gate signal of the LLC controller having almost half duty cycle. The gate signals for the master and slave converters are generated using the rising and falling edge instants from the original control gate signal of the controller, respectively. Therefore, the required 90 degree phase difference between two signals can be always kept at any instant and at any output load condition

High-order sensitivity invariants

Autor:

Jacek Izydorczyk

Resumen:

The aim of the research reported in this paper is to extend the notion of invariant sensitivity sum, widely known for electrical networks, from first-order sensitivities to high-order sensitivities. The results are high-order invariant sums of sensitivities formulated for nonlinear lumped circuit. Invariant sums actually found for nonlinear lumped networks are generalizations of sums given earlier for linear lumped networks

Design of a two-output forward converter with an output voltage objective function

Autor:

Yu-Kang Lo

Resumen:

A new method is proposed to distribute the steady-state output voltage errors in a two-output forward converter. The cross-regulation among the two output voltages aredescribed in terms of the circuit parameters. An objective function is formed for each of the two outputs to track its reference within the specified error. The weighting feedback gains of the two output voltages can be determined by the presented control scheme which optimizes the objective function. The proposed method is suitable for a two-output system without a dominant load

Two-dimensional recursive digital filters with nearly circular-symmetric magnitude response and approximately linear phase

Autor:

Ju-Hong Lee

Resumen:

A general structure using a cascade of two stages with digital all-pass filters (DAFs) for designing two-dimensional (2-D) recursive circularly symmetric digital low-pass filters (CS-DLFs). The first stage is a parallel connection of a 2-D DAF and a 2-D pure delay block. The second stage uses a parallel connection of a 1-D DAF and a 1-D pure delay block. Design results with nearly circularly-symmetric magnitude response and approximately linear phase can be achieved satisfactorily

A low distortion CMOS continuous-time common-mode feedback circuit

Autor:

Yen-Tai Lai

Resumen:

The paper proposes a high linear CMOS continuous-time common-mode feedback circuit. Theoretical analysis and SPICE simulation results are provided. Two circuit applications of the proposed configuration, one is the fully differential folded-cascode op-amp, the other is the Multiply-by-Two circuit which is the key component in the popular 1.5bit/stage pipelined ADC are designed. The Comparison results show that the new configuration has attractive characteristics concerning their implementation in high linear analog integrated circuits
