igbt gate
thank Fvm,
i am trying to design a buck chopper, so i think i require a good switching performance. please could you help with such a circuit, especially supplying both the negative and positive from the same source.
how to design an igbt drive
Hi everyone,
could anyone please recommend an IGBT to me, which does not require a negative gate voltage to turn off. if not, please could you help with a circuit showing how to easily supply +15V to the Vcc of my optocoupler and -10V to the Vee, from the same...
converter
Hi all,
i need a circuit with similar specification.
hope its ok posting my specifications here.
{
Vin=100Vdc;
Vout=150Vdc~400Vdc;
power=175W;
no isolation neccesary.
}
thanks in advance for your help.
designing boost converter
hi all,
please i want to design a boost converter
Vin=100Vdc;
Vout=150Vdc~400Vdc;
output power is 200W, max
please does anyone have circuit ideas, especially how to choose an appropriate inductor, seems to be a very important factor.
inverter for converting 12vdc to 230vac
ok, thanks.
but could you give any pointer as to how to go about the design of a such a boost converter.
i have tried simulating with SIMULINK, but it doesnt give the expected output.
16f877 dac output voltage
hi all,
please can you give a basic C code(MIKRO C) for pic16f877a, that would generate a sine PWM. and if possible, a brief explanation of how to change the output frquency would be appreciated as well.
N.B, i am relatively new to microcontroller, please be patient...
simulink boost
hi Darla1,
please could you also send me the simulink models, open and closed loop. would really appreciate it.
thanks.

boost inverters
Hi audioguru,
please can you help with the deisgn of a boost converter, converting a constant DC voltage of 30V, to an output of 100~300Vdc, with an output average current of about three amperes.
thanks in advance.
source code sine wave inverter
Hi Taner, nice work on the inverter.
but please, could you just post only the code that generates the sine pwm signals only, without any feedback, and assuming a modulation index of 0.8?... i would appreciate if you could do this, as i need to design a basic...
