Design plan of automobile electric water pump control
Infineon offers a variety of products, from microcontrollers, sensors and transceivers to intelligent power drivers. By integrating technical and system expertise, Infineon has become a trusted partner that can help customers achieve higher performance in engine management and transmission, thereby reducing fuel consumption and exhaust emissions. The aim is to achieve these goals while improving the driving experience.
Nowadays, emission reduction and fuel consumption are increasingly becoming the key to the future of the automotive industry. Rising oil prices and government regulation are one of the drivers of this trend.
Improvements in powertrain (current and hybrid) and transmission technology can reduce CO2 emissions by 20%. Engine, transmission, and hybrid options are mutually exclusive, so the Fleet average is used as a benchmark.
Infineon's contribution is not only to provide products, but also to enable partners to optimize their electronic system settings through support, demonstration boards, etc.
System advantages
Improve engine cooling control
Increased pump efficiency
Reduced power consumption
The speed can be adjusted according to actual needs
The motor is completely turned off when it starts, which speeds up the heating

High Frequency AC Power Supplies
High Frequency Variable frequency AC power supply converts AC electric to pure sine waveform by through AC – DC – AC conversion, which is different from variable frequency speed controller and common AC voltage regulator.
VFP-H series variable frequency power supply is manufactured under SPWM mode; it is designed by MOSFET module as active component, and adopts other technologies as digital frequency division, D/A conversion, instantaneous feedback and sinusoidal pulse width modulation to make the capacity of single unit up to 150KVA. Isolated transformer used to enhance total stability, strong load applicability, high quality output waveform, and simple operation, small size and light weight. In addition, this power supply has many protective functions against short circuit, over current, over load and over heat to ensure proper operation.
Comparing to traditional frequency inverter power supply, our inverter power supply removes the transformer and frequency converter, by using pure high-frequency conversion technology, with built-in by AC/DC and DC/AC parts, our AC inverter power supply could give stable AC output with prefect output precision.
Because, our new technology does not need transformer for conversion and isolation, the power supply size can be reduced within the same output power rating, and not limited by the transformer, output frequency could reach 15 ~ 1Khz continuously adjustable.
