High power density, high efficiency and high power. Abstract This paper presents the design of an auxiliary power distribution network for an electric vehicle.

World Applied Sciences Journal 21 2: With the Compare feature in Findchips Pro, members of the procurement and engineering teams can immediately see detailed breakdowns of the similarities and differences between any two parts.

The advantage of this configuration is that the 48Vdc voltage distribution network is more efficient than the usual distribution system. You have a Findchips Basic account.

Comparison between waveforms captured from the prototype and simulation results are similar. Capacitor Ripple Current Improvements Capacitor Ripple Current Improvements The multiphase buck regulator topology allows a reduction in the size of the input and put capacitors versus single-phase designs.

Honeywell Sensing and Control. Click on Series name for product info on aimtec. In today s applications, high surge currents coming from the dc bus are a More information.

This indicates that the simulation results are a good predictor for the experimental results. Figures 5 b and c show the inductor L1 and L2 current waveforms respectively. Introduction to power processing 1.


As seen in the Figures 8 and 9, voltage spikes occur when the switches are turned on or off.

Yellow, Visual Signal Type: A Vdc distribution network, although more efficient, was not considered an option because of safety issues V Auxiliary load current requirements The power requirements of loads that are datashet be retained in the xatasheet conversion need to be determined. Integrated Device Technology Inc. Preliminary calculations that were carried out showed that current consumption of these loads decreased significantly if LEDs were used.

Derivation of the flyback converter: As an initial step in the project, a dc-dc converter with a 30A output current has been built and the design procedures are presented in the next section of this paper.

Fatasheet meter is powered from the same bus that. Fairchild On-Line Design Tool: Balakrishnan 2 1 PG. The nominal battery voltage of the electric vehicle will be Vdc.

In an electric vehicle, energy efficiency is extremely important and therefore the auxiliary power network must be designed for high efficiency. The main object is to guide the designer in selecting. Most power supplies in the commercial world, however, are built with the bread-and-butter. Converter circuits Chapter 6. A Cuk converter has been designed and implemented that converts 48V to 12V at a maximum load current of 30A. To achieve a compromise between efficiency and component size, a switching frequency of kHz is used.

The meter is powered from the same bus that More information.

30CPQ100 Datasheet

Specifically, as the average current consumed in power steering is around 25A, one converter with a 30A output will be placed beside it to supply the power. The use of high efficiency LEDs and power supply current limiting results in datasheey energy consumption by the auxiliary loads.


Cuk Converter The basic requirements of the Cuk converter are listed in Table 2. The main object is to guide the designer in selecting More information.

By quantifying the input and put More information.

Not Compliant Min Qty: Senior Field Application Engineer. N 1, Rajashekher Koyyeda 2 1, 2 M. Another way of reducing power consumption in the car is to replace all the external and internal light bulbs in the vehicle, except headlights, with high intensity LEDs.

In addition, the 30cpq1100 and current waveforms in this converter are particularly clean, with very little ringing or overshoot, and therefore very little snubbing is required [1,2].

All other auxiliary parts were found to operate properly in the current limit tests; thus, the power ratings of the converters are decided based on the average current values of the loads.

Switch Push Button N. The leakage inductance of the power transformer Nondissipative lamping Benefits – onverters Even if small, a transformer s leakage inductance reduces the efficiency of some isolated dc-dc datasheeet topologies However, the technique of lossless voltage More information. This was verified from the tables and figures provided in the Philips Soft Ferrite data book [6].

The corner frequency the C filter is always. Download Part Footprints Directly from Findchips Jumpstart your designs with free downloadable part models in a variety of software formats, powered by Samacsys.
