This paper presents a single-objective model predictive control for bidirectional DC-DC flying capacitor (FC) converter, which integrates battery to the microgrid. The presence of multiple FCs facilitates converter interface low-voltage high-voltage DC bus at reduced voltage stress on its power switches. However, such requires controller that fulfils objectives, namely and FC regulations, flow....

A novel two-split capacitor (T-SC) array structure for Successive Approximation Register (SAR) analog-to-digital converter (ADC) is proposed. When used as digital –to-analog converter (DAC), this circuit reduced the chip area by 27.7% in comparing with the conventional Split Capacitor (SC) at resolution=14. The area reduction effect can be more significant with the increasing resolution of ADC....

This paper main intents to present a flying capacitor multilevel inverter based shunt active power filter(APF) with Sigma-Delta modulation. A multilevel Sigma-Delta modulation(SDM) control can be applied to control power section of APF intention to reducing sensitivity to flying capacitor voltage deregulation and mending modulator performance. In these control section of APF perfect harmonic ca...

We propose a new converter control scheme for a converter–inverter system. The strategy is to fully utilize the inverter dynamics in controlling the converter dynamics. We obtain the power dynamics for both converter and inverter systems, and control the converter power so that it matches the required inverter power exactly. Then, in the ideal case, no power flows through the dc-link capacitors...

This paper presents the topology known as isolated flying capacitor multilevel flyback converter (FCMFC). The uses capacitors (FC) for high-gain, DC-DC power conversion while maintaining primary-secondary isolation and improving efficiency capability of a standard transformer circuit. Three converters have been developed tested, one control, 3 level FCMFC, 4 FCMFC to prove gain benefits this ne...

-A dc-dc converter has its applications, such as in hybrid vehicles, solar inverters, in power supplies for microprocessors etc. A bidirectional dc-dc converter can be alternately operated as a step down converter in one direction of energy flow and as step up converter in reverse direction of energy flow, in places where both the sides have voltage sources. A high voltage supply using a single...

This article presents a hybrid boost converter architecture for improving the efficiency of light-emitting diode (LED) drivers used in mobile applications. By cascading low-switching frequency time-interleaved series–parallel switched-capacitor (SC)-stage with an inductive-boost converter, we facilitate lower voltage-rated switches, thus significantly reducing switching losses. Charge-sharing l...
