Hi All,
I have a doubt.
after rectification, we have two DC voltages. one is Pulsating Dc and the other is average DC.
which the exact DC voltage which gives 230Vdc.
How important the average DC in our calculations, when it has to be considered.
I hope this may be silly doubt but pls clarify
The output of Bridge converter is been used to drive Power MOSFET of Vds = 600V.
The MOSFET works as switch. so to provide such voltage i am developing this circuit

Also it will be helpful for me if I can get the formulas to calculate voltage and current at each segment of...
Hi all,
I want to convert 220VAC, 5A/50Hz to 230VDC, 3A
I am using the circuit which i have attached.
The components values which I chose are:
1:1 transformer
1N5406 diodes
150uF,400V electrolytic cap
Inductor - yet to be choosen
R of 115 ohms.
Pls, suggest whether this circuit configuration...
Hi All,
The attached circuit is the recent one in which Im working.
the problem with this circuit is if duty cycle is 100% the current delivered to motor is 0A and voltage is maximum and if duty cycle is 0 the current supplied is maximum and voltage is minimum.
could anyone tel me the problem...
I think diagram is not properly visible. You are right I connected SD,VSS and COM to ground and I replaced 1N4148 diodes with UF4007.
Inductor value is 400uH, 4A
Capacitor value is 100uF and 100V
Switching frequency is 300Hz
and Supply voltage to Drain terminal varies from 10 to 100V
The Vout...
I intend this circuit to work as variable buck converter. So based on PWM signal the output voltage should vary. for Eg, say I supplied 20V to drain so if PWM is 100% then output should be 20V if it is 50% then 10V.

this is my recent schematic in which Im working.
Also I tested the complete circuit as attached.. The output votage across the inductor is 5V pulsating DC..
I supplied supply voltage of 20v to Drain but the output is 5V...
Help me out to get the proper output
What happens if VS pin is not connected to junction point of Source of Q1 and drain of Q2?
Also I use 100nF ceramic capacitor and 1N4148 diode in Bootstrap circuit.
Does the voltage rating of cap and diode affects the working of DC-DC converter.
what should be the voltage rating of cap & diode...
The supply to the DC-DC converter is been given by 2 channel DC supply in which one channel supplies power 15 V to IC1, IC2 & IC3. The other channel is been used to power up the MOSFET.
Moreover after supplying power the signal at L0 pin (IR2110 IC) is available. but no signal at Vs, Vb, & H0...
Been tried as mentioned by ravindragudi and connected inductor in series with junction point of Q1 source and Q2 Drain does not functions as buck converter.
FYI, the circuit has to be variable buck converter
Hi All,
Does my attached circuit can work as variable DC-DC converter. If not help meto make the circuit as intended.
Thanks in advance:)
IC1 & IC2 is 555 timer
IC3 is IR2110
