Update!
Okay, after few days, i have design the pcb layout again. Finally it works. i have obtain desired voltage. But there is one more problem. when it charges the capacitor to desired 235 V, it stops charging. The capacitor starts decharging slowly. But it never starts new charge cycle. The...
here are my works. i have change somethings on pcb so it has worn a little bit.
- diode is rhrp30120
- mosfet is FR3710Z
- charged capcitor is 680uF 400V
- 150uF capacitor is electrolytic capacitor.
pcb has been manufactured by me by using photoresist pcb. after that all ways have been soldered.
First of all, thanks for these very helpful information and for sharing your experience. i ll design a new pcb and i ll consider your recommendations.
-The other reason can be arise from through hole components. Also i ll order low-ESR capacitors this time.
-For arduino, digital pin goes HIGH...
Hey guys im new here and this is my first message in this forum. i want to talk about some problems about the LT3750 capacitor charger.
Im trying to design a 240V 6A capacitor charger system. i have made calculations according to lt3750 datasheet. then i have construct the circuit in breadboard...
