查询词典 high voltage

When the load current lies within its normal range and Q2 is off, the magnitude of the supply voltage and the values of R3 and R4, which form a potential divider across the supply rails, determine the voltage at the reference input.

当负载电流在正常范围内Q2处於截止状态时，电源幅值以及R3和R4的值，穿过电源轨形成潜在分压器，决定参考输入处的电压。

For example, if R4 has a value of 10 kΩ, a trip voltage of 18V would require R3 to have a value of 62 kΩ. When choosing values for R3 and R4 to set the desired trip voltage, ensure that they are large enough that the potential divider will not excessively load the supply.

例如，如果R4值为10k，18V的跳闸电压需要R3阻值为62k.R3 和 R4选择适当的阻值来设置需要的跳闸电压值，确保它们足够大以至于潜在分压器不会过度负荷供应。

Do not supply power voltage higher than the rating voltage, which may cause fire or systematic damage.

We must microcontroller Device get is: 1 at all times be used to measure voltage and current of the A/D converter one under the command and provide the basis for the power transistor Voltage of D/A converter.

我们要从微控制器得到的是：一个在所有时间都用来测量电压和电流的A/D 转换器；一个根据命令为功率三极管提供基准电压的D/A 转换器。

A novel zero-voltage and zero-current resonant pole soft-switching inverter was proposed to achieve zero- voltage and zero-current switching simultaneously when main power devices turn-on and turn-off. Therefore, turn-on capacitive losses could be reduced for devices which the intrinsic capacitor value cannot be neglected. Additionally losses caused by the tail current can also be reduced, when IGBTs are used as main switches.

提出一种新型的零电压零电流谐振极型软开关逆变器，可以在主功率器件开通和关断时，同时实现零电压和零电流，因此对于内部电容不能忽略的器件，可减小容性开通损耗，当绝缘栅双极型晶体管(insulated gate bipolar transistor，IGBT)作为主功率器件时，也可减小拖尾电流引起的损耗。
