The main objective of this concept is to examine the operation of fundamental buck-based three-phase singlestage ac–dc full-bridge converters. In this concept, the operation of this fundamental converter is explained and analyzed, and a procedure for the design of its key components is derived and demonstrated with an example and general concluding remarks comparing Buck-Based and Boost Based t...

This paper investigates the impact of elite capture on the allocation of targeted government welfare programs in Indonesia, using both a high-stakes field experiment that varied the extent of elite influence and non-experimental data on a variety of existing government transfer programs. Conditional on their consumption level, there is little evidence that village elites and their relatives are...

(1) <(z1 · z2) = <(z2 · z1). (2) If z is a real number, then z + z3 = <(z) + <(z3) + =1(z3) · i+ =2(z3) · j + =3(z3) · k. (3) If z is a real number, then z − z3 = 〈<(z)−<(z3),−=1(z3),−=2(z3), −=3(z3)〉H. (4) If z is a real number, then z · z3 = 〈<(z) · <(z3),<(z) · =1(z3),<(z) · =2(z3),<(z) · =3(z3)〉H. (5) If z is a real number, then z · i = 〈0,<(z), 0, 0〉H. (6) If z is a real number, then z · j...

Electric traction system uses voltage source inverter technology for three phase electric locomotives. This paper proposes Z source inverters to control the speed of locomotive drives. The acceleration region and free running region of operation of locomotive is considered for analysis. The control strategy for Z source inverter used is simple boost control. The speed control method for tractio...

Renewable energy sources (RES) place main role in present days to generate power. The Switched Boost Inverter is a single stage dc-ac power converter, whose output voltage can be either greater or less than its input dc voltage. This converter can supply both dc and ac loads, simultaneously, which makes it suitable for micro grid applications. Also, this converter allows shoot-through of the in...

The practice of diagnostic x-ray imaging has been transformed with the emergence of digital detector technology. Although digital systems offer many practical advantages over conventional film-based systems, their spatial resolution performance can be a limitation. The authors present a Monte Carlo study to determine fundamental resolution limits caused by x-ray interactions in four converter m...

Assume that point evaluation is a bounded functional on H for each point z ∈ C, and also that H has the following symmetry property: H is closed under the operations f(z) 7→ f(z)(z− ζ)/(z− ζ) (provided f(ζ) = 0) and f(z) 7→ f(z). These assumptions ensure that H is a Hilbert space of entire functions in the sense of de Branges [4]. According to de Branges’ theory, there exists an entire function...

The operation, design and control of an isolated bidirectional DC–DC converter for hybrid electric vehicle energy management applications are discussed. Different operation modes and boundary conditions are distinguished by phase-shift angle and load conditions. The absolute and relative output voltage ripple was derived. The dead-band effect and safe operational area are further investigated. ...
