hi all
i want to control the boost conveter duy cycle using uC ATMEGA 8535
but when the duty cycle is 10 %the voltage increase
after i raise the dutycycle more than 10 % the voltage drop....
is it something wrong with my boost?? or because the frequency??
i use 3 KHz
when i use 31 KHz the mosfet is always on
i'm using an optocoupler to separate the mikro and boost converter,
the minimum output from optocoupler is always havea voltage to activated the gated so the mosfet always ON,
but if i using a smaller frequency thethe output from the optocoupler have...
okay thank you all,,,, but i still don't understand..
So to increase the current and the voltage it is depend on the inductor rated?? i have to increase it??
sorry i mean the 200v 9 ampere is the for maks output voltage in the motor DC load...
when just connected 7 volt the motor is already spinning, so with the voltage 15-30 v it wil be more fast.
i wantt to make the load spinn with (15-30v) and when i raise the duty cycle the spinnig getting...
what kind of diode that commonly used in boost conveter??
is it rectifier? schottky? or ultra fas switching diode?
and how to make the snubber circuit in boost converter for the MOSET and diode??
thanks before.
hi all,
i already make a boost converter for driving a load motor with specific : 200 v 9 ampere..
when the load is not connected the voltage can be up 200 v - 400 v but
when the load is connected the voltage output drop until below the input voltage
the output current is about 0.8 -1.1 A...
hey all,
i want to build a project boost convert 10 v ---> 200 volt, 10 A using SCR,
but when i looking for the schematic, i can't find schematic that using SCR ( the most is mosfet).
it is possible if i change the mosfet into SCR?
if it is..what type SCR should i use?? and how is the schema?
