另一個(gè)優(yōu)點(diǎn)是升壓轉(zhuǎn)換器級(jí)不需要隔離,所以也不需要考慮變壓器的復(fù)位時(shí)間,同時(shí)輸入電壓范圍可以遠(yuǎn)大于4:1。因此,輸入范圍不僅限于8:1(4:1接著4:1),而且可以達(dá)到12:1(8:1接著4:1)12:1輸入范圍DC/DC轉(zhuǎn)換器。非隔離升壓級(jí)之后是常規(guī)的4:1隔離式DC/DC轉(zhuǎn)換器。每個(gè)轉(zhuǎn)換器系列都可以在24V、28V、36V、48V、72V、96V或110Vdc標(biāo)稱電源電壓下工作,包括EN50155標(biāo)準(zhǔn)所定義的欠壓和過電壓瞬態(tài)。轉(zhuǎn)換器提供12V、15V、25V或48V的隔離輸出。 40W和60W版本也具有5V輸出。

傳感器供電
傳感器由主系統(tǒng)電源軌的DC/DC轉(zhuǎn)換器供電,通常只需要幾瓦的電壓即可運(yùn)行。系統(tǒng)標(biāo)稱電壓通常為110VDC,但有時(shí)可低至24V。多通道傳感器或驅(qū)動(dòng)執(zhí)行器的功率要求可能更高,達(dá)到40W。每個(gè)傳感器通常都需要單獨(dú)使用隔離式DC/DC,以保持較低的輸出電壓,并避免可能導(dǎo)致EMC問題的接地環(huán)路(例如傳感器交叉干擾)。但是系統(tǒng)電源軌并非 “干凈的” 。
the output power quality is better;
2) Modular parallel redundancy design is adopted, which is convenient for maintenance and high reliability;
3) According to the working characteristics of the shore power supply, the high-voltage side of the shore power supply has the function of preventing inrush current and limiting current. When there is no ship connection, the system loss is close to zero. When it is necessary to connect the ship, there is no inrush current at the moment of closing the high voltage, and the closing times are not limited;
4) The internal communication network adopts optical fiber network, with fast communication transmission speed and strong anti-interference ability;It can be expanded in the later stage. Multiple shore power systems are connected through optical fiber communication, and power balance, load balance and synchronous coordinated control are realized through shore power control system and output synchronous tracking phase-locked technology, which perfectly solves the demand of system expansion in the later stage. When the output capacity of the system is insufficient, it can be automatically connected to the grid for capacity expansion. When the capacity is surplus, it will be automatically cut off. When a single unit fails, it will be automatically cut off and derated.
