Power System Distribution01:25

Power System Distribution

Power system distribution involves delivering electrical energy from power plants to consumers through a network of transmission and distribution systems. The process begins at power plants, where energy from coal, gas, nuclear, water, and wind is converted into electrical energy. These plants use three-phase generators, typically rated between 50 to 1300 MVA, with terminal voltages ranging from a few kV to 20 kV, depending on the size and age of the units.
The transmission system is designed...
Maximum Power Transfer01:16

Maximum Power Transfer

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...
Power Factor Correction01:20

Power Factor Correction

The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.
Electrical Power01:07

Electrical Power

Electric power is the product of current and voltage, represented in units of joules per second, or watts. For example, cars often have one or more auxiliary power outlets with which you can charge a cell phone or other electronic devices. These outlets may be rated at 20 amps and 12 volts, so that the circuit can deliver a maximum power of 240 watts. Consider a 25 Watt bulb and a 60 Watt bulb. The conversion of electrical energy produces heat and light, while the kinetic energy lost by the...

Control of Power Flow

There are several methods to control power flow in power systems:
iChip01:24

iChip

The cultivation of environmental microorganisms has long been hindered by the inability to replicate complex native conditions in vitro. The isolation chip (iChip) addresses this limitation by facilitating the growth of previously uncultivable microorganisms through in situ incubation. Designed for high-throughput microbial cultivation, the iChip comprises hundreds of microchambers, each capable of housing a single microbial cell. These microchambers are loaded with a mixture of molten agar and...

Area of Science:

  • Electrical Engineering
  • Computer Engineering

Background:

  • On-chip wireless communication systems (OWCS) integrate multiple subsystems like 2nd-generation (2G), 3rd-generation (3G), and long-term evolution (LTE).
  • Improving power efficiency in OWCS is critical for mobile and embedded applications.

Purpose of the Study:

  • To design and present a System Power Control Unit (SPCU) architecture for optimizing OWCS power consumption.
  • To enable independent power management and dynamic voltage and frequency scaling (DVFS) for individual subsystems.

Main Methods:

  • Implementation of an SPCU with interrupt-driven sleep and wake-up mechanisms for 2G, 3G, and LTE subsystems.
  • Utilizing real-time sleep timers or Global System for Mobile (GSM) communication sleep timers for subsystem arousal.
  • Independent voltage and frequency configuration for each subsystem during normal operation.
  • Integration of a voltage supply monitor for real-time voltage guarding.
  • Hardware-based automatic DVFS implementation for subsystems.

Main Results:

  • The proposed SPCU effectively manages the power states (sleep/wake-up) of 2G, 3G, and LTE subsystems.
  • Independent configuration of voltage and frequency for each subsystem is achieved, unlike previous sole voltage supply methods.
  • The voltage supply monitor ensures real-time voltage stability within the OWCS.
  • Automatic DVFS implementation by the SPCU leads to dynamic power optimization.

Conclusions:

  • The developed SPCU architecture significantly enhances power efficiency in OWCS.
  • The independent power management and DVFS capabilities offer granular control and optimization for diverse communication subsystems.
  • The SPCU provides a robust solution for reducing energy consumption in modern wireless communication systems.
