[introduction] inserting electric type electric car (in PEV) system, charger can divide for 3 level: AC Level 1 (<1.92 KW) , AC Level 2 (<19.2 KW) and DC Level 3 (>19.2 KW) . 1 as a result of its bulk and weight, do not suggest to be in high power uses a car to carry charger in 3 class system. Inserting electric type electric car (in PEV) system, charger can divide for 3 level: AC Level 1 (<1.92 KW) ,…
[introduction] the article introduced new-style 950V IGBT and diode technology. 950V IGBT structure is based on small groove concept, compare with photograph of typical 1200V technology, the static loss of new-style 950V IGBT and diode and / or switch loss is reduced significantly. Use the reciprocity of demand and power module design through the analysis, the applied outcome that the article determined power module and optimize method. Profit from is designed via optimized power module and use 950V technology, the…
[introduction] switch power source uses high-power to control switch canal to undertake high-speed guides through circuit namely with end. Offer alternating current of high-frequency of dc translate into transformer to undertake transformation, group or the one much group tension that produce a need thereby. One, brief introduction of power of switch power source Switch power source uses high-power to control switch canal to undertake high-speed guides through circuit namely with end. Offer alternating current of high-frequency of dc translate into…
[introduction] in recent years, as the flying development of science and technology, from ” make ” to ” wisdom go to ” the story of transition is being performed quickly in the whole world. No matter be the information of sleek automatic chemical plant or digitlization,run a system, without be absent reveal wisdom the arrival that creates a period. However intelligence makes this thing be in 20 centuries before 60 time, it is so easy to can be done not…
[introduction] global mainstream railway system presents much voltage power supply, bring about power source module cannot normalization realizes report to maintain a function, raised cost of the design difficulty of client application system and government. For compatible exceed wide full voltage to input limits and capacitance normalization, the dominant position that Jin Shengyang uses own IC invented a kind active drop report to maintain circuit. The actor defect that the article adopts plan of power source of on analytic market…
[introduction] reliable voltage monitor the trade demand that IC is industrial group from beginning to end, because it can raise systematic dependability, change in voltage twinkling and the system promotes property when power source breakdown. Semiconductor manufacturer also is raising voltage monitor ceaselessly the function of IC. Monitor IC need calls electrify restoration (VPOR) lowermost voltage a future life becomes clear or reliable restoration signal, and before voltage of this lowest power source comes, the condition of restoration signal is…
[introduction] the thermal resistor element that NTC has negative temperature coefficient as a kind, be measured in temperature feeling and is wide application in circuit protection. And in using a design actually, the applied setting of NTC each different, some jobs setting is very complex, this has thorough make a thorough inquiry with respect to the applied detail that needs pair of NTC. Depend on rich product and applied experience, the engineer of Vishay can help everybody solve the mixed…
[introduction] the core index that ripple is power source, the ripple noise that how reduces power supply is the problem that most user cares, it is from power source design, exterior circuit does plan to improve on one hand, should have on the other hand more accurate the more appropriate method that checks ripple noise. The ripple of power source and noise introduce Ripple and noise namely: The is the same as frequency with mains switch frequency wave motion of…
[introduction] before two articles were discussed all sorts of advanced drive support system (the phylogeny of ADAS) . Last article of this series sleeps introductory driver monitoring and be addicted to the system that monitor, this is considered as full automatic one of driving crucial requirements. Next, we replace discussion sweep and rearview mirror. We will discuss technical tendency of future finally, the car that includes software definition and virtual reality and enhance reality. 01 be addicted to sleep the…
[introduction] – is dedicated on July 8, 2022 the global semiconductor that tastes newly at introducing and electron yuan cent of accredit of parts of an apparatus sells trade lustre electron (ground of Mouser Electronics) special honor announces to obtain Vishay Intertechnology of manufacturer of famous electron component at the same time, inc. 3 when issue large award. These 3 award it is 2021 year America respectively excellent service cent sells America of business, 2021 year cent sells excellent service…
