冷啟動VS軟啟動 cold start v.s soft start

想請問cold start和soft start 兩種是一樣的東西嗎?

有什麼差別嗎?還是指用的地方不同呢?

1. cold start:

The outdoor units of microwave wireless telecommunication systems set on the roof of

many buildings may have to start and continue working at –40 oC during winter.

Therefore, it is necessary to guarantee the DC/DC converter will turn on at –40 oC.

Sufficient design margin is needed to tolerate the temperature coefficient of ICs and

discrete semiconductor components in order to work in wide operating temperature ranges.

Calex has verified full operation at low temperatures.

This ensures that the user won’t have system issues at low temperature

2. soft start:

An inrush current and overshoot voltage appears

in the startup period of the DC-DC converter,

which may causes damage to the whole system and the load.

Thus, a so called soft-start function is adopted during the

startup stage of the DC-DC converter, which smoothly

conducts the output voltage and current in the inductor to the

steady state.
