The class of Deterministic Conditional Term Rewriting Systems (DCTRSs) is of utmost importance for the tight relationships exhibited with functional programming, logic programming and inductive reasoning. However, its analysis is extremely diicult, and to date there are only very few works on the subject, each analyzing a particular aspect of DCTRSs. In this paper, we perform a thorough analysi...

⎯ A thermoelectric energy scavenging microsystem is proposed, optimized to convert the small thermal power available in human-body applications. A Lithium solid-state thin-film battery is integrated in the same device as well as the ultra low-power electronics to charge battery and perform DC-DC conversion.

Dc-dc converters suitable for use in battery-powered electronic equipment with energy management are discussed. To realize the benefits of energy management, these converters must be capable of maintaining regulation of their output voltages at no load, while maintaining high efficiency. Variable frequency operation is shown to give an improvement in efficient operating range of approximately t...

This paper includes modeling and simulation of 180 MW units of pumped storage power plant with Variable speed machines. In this method, voltage source inverters are used instead of traditional cyclo-converters. This paper aims to control the voltage source inverters and maintain DC voltage at a constant value. AC/ DC/ AC converter is used in system configuration structure in order to control an...

In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...

The circulating current is one of the important issues for parallel converters. It affects system stable operation and degrades power quality. In order to reduce converter harmonic pollution grid, a new suppression strategy proposed source without any communication line. This able realize sharing between modules by changing external characteristics thus suppress among control adopts DC-side dro...

The paper proposes a novel interleaved AC-DC ZCS-PWM boost converter that requires the use of just single active auxiliary switch to assist in turning off main power circuit switches with ZCS. can be turned on and ZCS its allows operate without an increase peak current or voltage stress. is for much shorter time than most other converter, which at higher levels previously proposed switch. conve...

DC-DC converters are switched power converters. They are used to convert one DC voltage to another DC voltage. It is inordinately used in industry as well as in research. The model of converter system varies from the ON state to the OFF state. The major drawback of the boost converter is the uncontrolled supply of voltage and current. So initially convectional PID controller is designed to regu...
