how does current flow through a capacitor when there is dia electric material in between positive and negative plate,
and why does current lead in capacitor with respect to voltage when there is a little flow of current?
All right that means 4N35 will create problem in future , OK i will not use that , I will use TLP250 bit how to drecrese overshoot in that case ?
The overshoot is near the mosfet voltage rating that burn mosfet some time ;
and one more thing does voltage overshoot produce more heating or what...
Re: Difference between TLP350 & IC4N35
due to cost have to use only mosfet ; not inductor and freewheeling diode ; it is just simple pwm based charger not mppt based .
My question is that when i am using 4N35 why is there no overshoot in the same sircuit , is that 4N35 is more effective...
Yes I am using 4N35 as agate driver of mosfet and the circuit is simple pwm solar charger ; it consist only mosfet as a switch between solar input and battery as output .
Difference between TLP350 & IC4N35
hi friends ;
I am using IC TLP350 for MOSFET driver than I am getting very high voltage overshoot on Drain But when in the same circuit I use IC4N35 as a MOSFET driver there is no voltage overshoot , what may be the problem with TLP350?

HI friends ; i am facing a problem in 10 KW PCU ;in this system there is an inverter of 10 KW and solar mppt charger of 10kw panel; functionally system is ok . independantly charger works fine as well as inverter but when i run inverter +solar charger the ripple current at inductor of solar...
HI friends ; I have problem regarding Regulator 7805 . In my circuit i m giving 12V input to 7805 and taking less than 0.5 A current at output but the regulator heat so much what is the problem
Friends I m using LM358 in differential mode amplifier for Dc current sensing ,with below details
Gain=51, non inverting mode, Vcc =+5V , In some LM 358 i am getting 100mV output volt with any input then i change the IC in the circuit and the other IC LM 358 works fine . I want to know is it IC...
Hi friends;
I have requirment of switch like Relay or contactor for following specification
Operating Volt =12V DC
Continuous Current = 70A DC
Voltage =170V DC
What should be the best option for this spec ? and please suggest me the part number of that component .
Hi friends;
I want to ask that when invereter is running at full load , battery is discharing with some amp suppose 50A . my question is that will this discharging current and ripple current will have value ?
& is this ripple current will decreases with incresing value of...
Sunnyskyguy ; Is is necessary to match impedance ? Because while designing buck converter we did not do any calculation for impedance matching . If it is necessary how to do this?
it is operated in pulsed mode . actually i want to know that if MOSFET is operating at 70 deg heatsink temp will it derate or leak the mosfet after some time so next time the mosfet could burn in SOA region?
Hi friends;
I am using MOSFET IR840 in a solar charge controller . I have placed a heatsink for cooling purpose . when charger run continuously for 4-5 hour heatsink temp raise to 70 deg at 30 deg ambient . I question is that how could i calculate the derating of mosfet ? so...
Thanks for your reply .
Hi Goldsmith ;
I dont have the schematic right now but i can tell you detail ..Capacitor value is .1uf and 22uf in parallel .
Frequency of PWM is 20KHz . and Will you please explain me what is modulation depth ?
