電流不足 電壓足夠 如果增加 ??(太陽能板)

我參加左個太陽能船比賽,發覺電壓足夠,但電流不足

有何辦法解決??

打錯字 標題 電流不足 電壓足夠 如*何*增加 ??(太陽能板)

更新2:

把電阻降低... 增加就易姐.... 減少有咩辦法

✔ 最佳答案
發覺電壓足夠,但電流不足, 係太陽能板唔夠, 或你隻船用電勁。
不可以降低電阻, 重死。增加電阻冇用, 又死。電阻無關。
試加一隻或並聯幾隻電解電容2200uF(容易買)在電壓兩端試下。其實你線路應有電容器作穩流, 可能你冇加或者唔夠大。

唔得就祇有一個方法就係加太陽能板, 並聯。冇計。

Voltage enough when there is no load.
If there is loading and current and voltage drop, it is because the power rating is not enough.

You can:
A. Use more Solar Panel, connect them in parallel.
B. Change Large Solar Panel.

Tell us more about your project, we may help.
1. What solar panel are you using? Voltage and current.
2. What kind of motor you are using? Volage and free running/ no load current.
Make sure the motor can run by a power supply/ dry battery with same solar panel rating.

我唔係幾明白,太陽能板電壓足夠電流不足?
如果太陽能板有負載時輸出電壓足夠就證明功率冇問題,而電流不足係因爲負載摩打太細,你將摩打加大即可。
最重要就係匹配問題,太陽能板輸出功率一定要大過負載功率5% ~ 10%

如果太陽能板有負載時輸出電流不足,電壓又不足就證明功率有問題,而係因爲負載摩打太大,你將太陽能板加大加多即可。
