Hi all
Please any can give me a hand , I implemented buck converter to use it as power matching between solar photovoltaic ( open circuit voltage is 20 V and operating current is 0.26 A) to electrolyser (operating voltage is 3V and operating current is 3A) . the switching pulses of the buck converter switch is generated manually by other IC circuit so I change the duty cycle manualy . The problem I have is when I adjust the duty cycle at defferint value from 0 to 1 the converter out put voltage is fixed by the load (at electrolyser operating voltage around 3V) but the current doesnot exceed the 0.25A , the converter has effeciency between 65 % to 85%.
if there is further Q I will make it clear.
Thank you very much for your help.
