On-board charger for electric vehicles (EV)

Most on-board chargers for e-vehicles operate on a voltage of 100-240 volts AC and have an output power of 3-11 kilowatts (kW).

An on-board charger for electric vehicles is a device that is integrated into the vehicle and charges the battery when no charging station or wall box is available.
It works with alternating current and converts it into slip current, which charges the battery. The charger can either be built into the vehicle itself or added as an aftermarket accessory. The voltage and power range of a charger can vary depending on the make and model of the electric vehicle. However, most on-board chargers for e-vehicles operate on a voltage of 100-240 volts AC and have a power range of 3-11 kilowatts (kW).

电动汽车车载充电器 (EV)

电动汽车车载充电器是一种集成在车辆中的设备,在没有充电站或壁箱的情况下,负责为电池组充电。它通常使用交流电源并将其转换为直流电源为电池充电。充电器既可以内置到车辆本身,也可以作为售后配件添加。车载充电器的电压和功率范围会根据电动汽车的具体品牌和型号而有所不同。然而,大多数电动汽车车载充电器的工作电压范围为交流100-240伏,输出功率范围为3-11千瓦。

一些高端电动汽车可能会配备更高输出功率的车载充电器,最高可达22千瓦或更高。这些充电器通过利用最新的电力电子设备和智能充电算法,最大限度地提高能量转换,并显着缩短充电时间,从而发挥了重要作用。

用于太阳能逆变器的碳化硅肖特基二极管SICW20C120

Silicon Carbide Schottky Diode SICW20C120

夏季是充分利用太阳能量的完美季节。太阳能不仅我们的免疫系统被激活,也令光伏系统处于最佳状态 - 就像德欧泰克德国总部屋顶上的光伏系统一样。而碳化硅肖特基二极管,如SICW20C120就可以减少太阳能逆变器中的损耗。

太阳能逆变器将太阳能电池板产生的直流电(DC)转换为交流电(AC)。功率电子组件就需要在非常高的频率下作高压的开关动作; 在这情况下, 续流二极管和IGBT中的开关损耗就变得非常重要了。基于碳化硅 (SiC) 的肖特基二极管可以设计用于非常高的阻塞电压。而它们提供的反向恢复时间几乎为零(更准确地说,必须说是容性放电时间)。这大大降低了二极管本身和IGBT中的开关损耗。德欧泰克的 SICW20C120 是采用TO-247封装的2x 10 A / 1200 V SiC肖特基二极管。其电容存储电荷通常仅为41 nC,可确保所需的快速开关时间,从而降低开关损耗。

Power Transistor 2SC2983 Reliably Controls LED Indicators

Power transistor 2SC2983

Summertime is two-wheeler time. Modern LED lamps in indicators, brake lights and rear lights ensure safety. The 2SC2983 is a bipolar power transistor for driving such LEDs.

Modern LED bulbs in indicators, brake lights and tail lights offer more brightness, durability and efficiency compared to conventional bulbs. The 2SC2983, from Diotec is a 1.5A, 160V NPN power bipolar transistor. It is an ideal component for the constant current regulators used to drive these LEDs. The TO-252AA/D-PAK housing design is compact on the one hand and offers a large cooling surface on the other hand for dissipating the thermal power loss, which can be up to 15 W. This increases service life and reliability. But other switching and amplifier tasks can also be implemented with this component. Used in the LED driver, the 2SC2983 ensures reliable light – for more safety and driving pleasure!

功率MOSFET DI100N10PQ 在电动自行车上的应用

Power MOSFET DI100N10PQ

尤其是在夏季,越来越多的人转向电动自行车,作为一种环保的替代汽车,无论是上下班还是休闲。仅在德国,2022年就售出了220万辆电动自行车。德欧泰克的功率MOSFET DI100N10PQ可用于高性能电动自行车的驱动。

电动自行车的成功本质上是基于锂离子电池的发展。如果电池不能在长途旅程中为系统提供持续的动力,那么最强大的马达也很难引起人们的兴趣。

因此,购买电动自行车时,您应该同时注意电池质量(充电容量)和电机的功率。对于城市自行车,50 Nm 就足够了,而山地自行车则需要高达 85 Nm。对高级电动自行车手就需要大约300-400瓦了。对于无刷直流电机驱动器,德欧泰克最新的QFN5x6功率场效应管 DI100N10PQ 是完美的选择。它提供仅4.5 mΩ的导通电阻,另外QFN5x6的封装也使得它拥有较小的体积。

Silicon Carbide Schottky Roadmap

Parts for high switching frequencies and voltages

Silicon Carbide Schottky diodes feature a high reverse voltage (650 V ... 1200 V) combined with an extremely low "reverse recovery" better say capacitive charge and thus discharging time. That makes these parts ideally suited for all applications, where high voltage levels are switched at very high frequencies. Typical application include charging systems for electric vehicles (EV), solar inverters or telecom power supplies.

你知道第一台割草机早在1995年就进入了市场吗?

ESDALC208 ESD Protection Diode

很难想象如果花园没有机器人割草机,当机器人割草机在草坪安静的工作,可以保持草坪又短又好。近年来,这些智能的自动装置引发了草坪护理领域的一场真正的革命。它们完全自动地接管了修剪草坪的任务,使我们不必自己动一根手指就能保持花园的完美状态。在这个过程中,他们为我们节省了很多时间,我们可以用这些时间做其他事情。

1994年,瑞典公司Husqvarna取得了一个小小的轰动:他们开发了第一台全自动机器人割草机。受自然界食草动物的启发,其原则是更频繁地修剪草坪,但每次只修剪一点点的草长。1995年,该机型以5,500马克(2,812欧元)的价格上市。

M而现代机器人割草机就需依靠可靠的 ESD 来保护无故障运行。德欧泰克的 ESDALC208 采用SOT-26外壳,是一款ESD保护二极管,可同时保护四条数据线。按IEC 61000-4-2的标准,它的空气/接触放电额定电压可达到±15 kV / ±8 kV,所以是适用于机器人割草机,此外,它也是工业应用中便携式电子产品的理想选择,例如用于打开车库门的遥控器以及用于控制灯光,百叶窗或供暖和空调系统的智能家居传感器。

一片绿茵茵的 – 德欧泰克的功率MOSFET DI114N06PQ应用在电动修剪器上

N-Channel Power MOSFET DI114N06PQ

终于又回来了,阳光明媚的日子。在德国德欧泰克的总部,一切都在生长,郁郁葱葱,包括家庭花园的树篱。当涉及到维护树篱,灌木和灌木,电动修剪机是一个非常有用的工具。在它的帮助下,修剪和修剪植物变成了孩子们的游戏。

电动修剪机的使用可以追溯到很久以前的历史。早在古埃及和罗马时代,简单的剪刀或镰刀就被用来修剪树篱和植物。反过来,树篱修剪器的发展也受到了修剪艺术的显著影响。树篱和灌木的几何形状或图形的艺术设计。园艺艺术影响了对专业电动修剪机和精确切割技术的需求。

我们的 N 沟道功率 MOSFET DI114N06PQ 非常适合电动修剪机等电动工具中的电机控制应用。正常下可达到 114 A 和 60 V,具有低导通电阻、快速开关时间和极低热阻。标准阈值电压可防止错误导通,这对于无绳电动工具尤为重要。除电动工具外,德欧泰克的功率MOSFET DI114N06PQ 也适用于各种工业应用,包括DC-DC转换器、同步整流器、电动工具等等。
