Use 350V electrolytic capacitos in series. Effective capacitance will be half the capacitor used.
You won't get electrolytic cap. more than 400V rated.
Capacitor value will be 1000uF for 1 Amp o/p current
Hello All
If the O/P is square wave you can choose RC low pass filter cut off = 10 * Fo/p max ( Fo/p max is Max O/P frequency )
This is thumb rule.
If your O/P is having pull up resistor use that as R & calculate C for desired cut off.
You can add schmidt trigger after LP filter. It will...
push pull dcdc
Check ringing frequency .refer to Unitrode app note on snubber design you can calculate values of res. & cap.
First check leakage inductance of your transformer.
Increase value of gate resistor to reduce rise time / fall time. This will also reduce ringing. But increase heating...
50hz pushpull
I am making Push Pull type 50Hz inverter using PIC16F883
I configured uC in half bridge mode for 20 mSec. period
1) Signals I am getting on P1A & P1b is just complement of each other.
Suppose for 30 % duty cycle without any deadtime what I am getting...
half bridge pwm
I am using PIC16F883 for my Push pull Inverter project
I am using PWM module configured for Half bridge
my inverter frequency is 50 Hz. fixed ( Period 20 mSec. )
so I set system frequency to 500 KHz internal oscillator any higher value is not possible
1) for Half bridge PWM...
I am using DS1307 & 24LC256 in my project ,my problem is at power on my uC89S52 read both chips one after other & it reads FFh when I read again it reads normal I have inserted 2 sec delay at startup still it dose same I have to read it second time to get correct data then onwards it works fine...
