“…Due to the long conduction time of the freewheel, the inductor current will drop sharply [22], which will lead to continuous conduction in subsequent cycles to maintain the output voltage stability. Once this happens, the loop will be disordered, and the output voltage ripple will become larger [23].…”

DC-DC (direct current controlled direct current) converter is the core control circuit in the field of power electronics technology. Based on the theory of sensors and MEMS (microelectromechanical systems), this paper constructs a DC-DC converter device integration and packaging model and proposes an enhanced current equalization technology with offset correction function suitable for two-phase DC-DC converters. Aiming at the generation mechanism of the output ripple of the two-phase DC-DC converter, the model adopts the ripple elimination technology based on the interleaved synchronous clock and the self-calibration interleaved time generator, so that each phase of the converter is accurately staggered within the full-load range, and the problem of output ripple amplitude is solved. During the simulation process, a high-performance two-phase DC-DC converter chip is designed and implemented, which includes an adaptive on-time control logic based on ripple feedback, a self-calibrating zero-current turn-off circuit, and a robust power switch transistor drive logic. The experimental results show that the full-load current of the chip reaches 6A, the peak efficiency is 91%, the phase-to-phase current error is <0.6%, and the output ripple is <9 mV. In the 90.265 V AC input, 0-10 W load range, the output voltage error is less than 0.96%, when the load is switched between no-load and full-load, and the system response speed is less than 200 ps, which effectively improves the overall performance of the DC-DC converter.

We present in this paper design considerations and implementation challenges of a proposed versatile SoC/SiP sensor interface intended for industrial applications. The proposed interface involves high-voltage circuits such as class-D power amplifiers, gate drivers, level shifters, and electrical isolators. Also, it includes low-voltage blocks like programmable gain amplifiers and ADCs. In addition, DC-to-DC converters are used to supply the various building blocks of the projected sensor interface. The key challenges for implementing each block are discussed in this paper. Also, the technological aspects to support the proposed SoC/SiP solution are given. Moreover, the different available packaging technologies to implement the intended SiP solution are discussed in addition to the thermal aspects associated with the system packaging.INDEX TERMS Industrial applications, sensor interface, versatility, system-on-chip (SoC), system-inpackage (SiP), thermal management.

This paper presents the design and analysis of combining input-voltage feedforward and proportional-integral (PI) controllers to regulate the output voltage of DC-DC Buck converter subject to input line disturbances. Non-idealities of the Buck converter such as passive and active components parasitics are included in the mathematical model obtained by the statespace averaging (SSA) technique for accurate control. The stability boundary locus approach is used to graphically analyze the system stability. It guides the design of the PI controller gains and the feedforward scaling factor to achieve desired phase and gain margins. Analysis shows that the feedforward scaling factor affects the stability regions of the closed-loop system and can limit the possible PI controller gains for certain phase and gain margins; 75 o and 9.54 dB in our case. The results are verified by a Simulink model developed for the Buck converter system.
