Power dissipating automotive control module

2008 11th Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems, 2008
Thermal performance of a high-power (>1 kW peak) automotive electronics module was evaluated using ANSYS' ICEPAKtrade Computational Fluid Dynamics (CFD) software. The module exchanges heat with cooling air via a plate-finned aluminum heat sink. To confirm the CFD model, the numerical air exit temperature results are compared to that of using the mass ...

Resistor Dimensions and Power Dissipation

IEEE Transactions on Parts, Materials and Packaging, 1965
In this paper a mathematical expression is derived representing the relation between the hot spot temperature and the dimensions of cylindrical axial lead resistors. The validity of the formula is discussed. Practical values for dimensions and material constants have been chosen and for 3000 combinations of these values the maximum temperature has been

Thermodynamics of Power and Dissipation

Israel Journal of Chemistry, 1977
AbstractCan one provide a thermodynamic theory for processes which occur with finite rates? We discuss a possible approach based on expressing the first and second laws as rate equations. The result is a first law formulated in terms of power and a second law in terms of rate of energy dissipation.

Efficiencies and Power Dissipation

1991
As a rule, hydrostatic transmissions are more efficient than equivalent valve-operated flow controls. The choice of pump configuration can, however, significantly affect power efficiency. In Section 5.2, four basic valve control circuits were described; meter-in, meter-out, meter-in/meterout and bleed-off. In the bleed-off circuit, the pump operates as

Sources of Power Dissipation

2014
This chapter presents various sources of power dissipation. At the outset, the difference between power and energy is explained, because most of the time when we say low power, we actually mean low energy. Various sources of power dissipations, both static and dynamic, are introduced first.

Gate speed improvement at minimal power dissipation

Asia-Pacific Conference on Circuits and Systems, 2003
We introduce a new gate sizing rule for significantly improving the speed performance of static logic paths designed in submicron CMOS technology. This methodology is based on the definition of local gate sizing criterion. It is directly deduced from analytical models of the output transition time and of the short circuit power dissipation, which are ...

Power dissipation of CMOS ASICs

[1991] Proceedings Fourth Annual IEEE International ASIC Conference and Exhibit, 2002
High levels of power dissipation in CMOS ASICs are a result of high speed and complexity which exacerbates numerous design issues due to elevated junction temperatures. A method of calculating total power dissipation, as viewed from the gate level in an ASIC design methodology is presented and the effects of power dissipation are examined.

Reduction of Functional Power Dissipation

2004
In chapter 3 reversible and irreversible processes as well as reversible and irreversible logic have been discussed. From this discussion it became clear that logical reversibility and quasi-statical changes of states are necessary boundary conditions for physical reversibility.

LIMITS ON ADC POWER DISSIPATION

2006
The need for low power A/D conversion in a large number of applications has fueled a trend towards ever-improving ADC power efficiency. This article investigates practical limits to this development by analyzing the minimum power needed in the constituent building blocks of today’s ADCs.

Reduction of Parasitical Power Dissipation

2004
In chapter 3 the parasitical power dissipation, consisting of leakage power and short-circuit power, has been discussed. The parasitical power is dissipated without attributing to the actual changes of the internal circuit states. In this chapter solutions to reduce the leakage power and the short-circuit power will be discussed in section 5.1 and 5.2,
