Power Quality Improvement in Traction Power Supply Networks
AC railway traction loads are usually huge single phase loads. As a result, a significant amount of Negative Sequence Current (NSC) is injected into utility grid. Moreover, harmonics and consumption ofreactive power are further power quality problems that the supply network is encountering. In this paper, acompensation strategy with the aid of Railway Power Conditioner (RPC) is proposed to over...
متن کاملParametric Power Supply Networks
Consider a graph G in which each vertex is either a supply vertex or a demand vertex and is assigned a supply or a demand. Such a graph G is called a power supply network. All the supplies and demands are nonnegative constant numbers in an ordinary network, called a steady network [1].This thesis introduces a parametric power supply network, in which all the supplies and demands are functions o...

متن کاملRecent Topics in Power Management Circuits
This paper summarizes recent research at the author’s laboratory into power management circuitry, including: (1) Envelope-tracking power supplies for base station power amplifiers, (2) Digital PWM generator circuitry, (3) Spreadspectrum clocking for EMI reduction in digitally-controlled power supplies, (4) High-efficiency coupled-inductor DC-DC converters with fast response and low ripple, and ...
متن کاملEmbedded power supply for low-power DSP
The use of dynamically adjustable power supplies as a method to lower power dissipation in DSP is analyzed. Power can be reduced substantially without sacrificing performance in fixed-throughput applications by slowing the clock and lowering supply voltage instead of idling when computational workload varies. This can yield a typical power savings of 30–50%. If latency can be tolerated, bufferi...
