Modeling, design, control and validation of a multiple-input DC-DC converter topology for effective renewable energy management
… control. A novel multiple-input single-output DC-DC converter topology is proposed for effective energy management. The topology is designed depending on the conventional structure of boost and buck converters and benefits greatly from this combination. Effective energy management …

An energy buffer for constant power loads
Constant power loads (CPLs) are a class of loads steadily increasing in use. They are present whenever a load is regulated to maintain constant output power, such as with LED drivers in high quality lighting that is impervious to input fluctuations. Because CPLs exhibit a negative incremental input …

THE CRISPRATOR: A FEEDBACK CONTROLLER IN MAMMALIAN CELLS FOR ROBUST PERFECT ADAPTATION
… Adaptation (RPA), i.e. the ability to maintain a constant output level despite changes in the environment. In Control Engineering, RPA can be achieved by mechanisms like integral feedback control, a specific implementation of Negative Feedback loops. However, the engineering of synthetic …

An Optimization-Based Framework for Designing Robust Cam-Based Constant-Force Compliant Mechanisms
Constant-force mechanisms are mechanical devices that provide a near-constant output force over a prescribed deflection range. This thesis develops various optimization-based methods for designing robust constant-force mechanisms. The configuration of the mechanisms that are the focus of this …

Designing and Implementing a Micro-controller based Primary-side Sensing Flyback Converter for LEDs Driver
… low cost, and its ability to provide a constant output current, a necessarily important factor to an LED driver. Meanwhile, the PIC18F micro-controller series offer numerous advanced features which include but not limited to pulse-width modulation (PWM), 10-bit 13-channel …

Load-Independent Class-E Power Conversion
… was presented in 1990 for maintaining ZVS and output voltage under a given load change without tuning any parameters, and it was validated with experimental results recently. The operating principle of this special design (inconsistent with the conventional design) is not elucidated in the …

Design of Microwave Front-End Narrowband Filter and Limiter Components
… two modes of operation in the on state: a constant output power mode and constant attenuation mode at high power. A third-order filter-limiter with center frequency of 870 MHz was demonstrated. It operates passively from incident microwave energy, and can be primed with an external voltage …

Opacity Verification and Fault Diagnosis in the Framework of Switching Output Automata
… In practice, external observers see piecewise-constant output signals (power consumption levels, alarm indicators, aggregate measurements) together with their durations, rather than internal state transitions or continuous trajectories. Classical discrete-event models capture event sequences …

Modeling and Design of Digitially Controlled Voltage Regulator Modules
… occupy large silicon area. Single phase digital constant on-time modulation method is another good candidate to improve the DPWM resolution without adding too much cost. However, directly extending this method to multi-phase application, which is the prevalent structure in VRMs application, will …
