Signal SPWM (Sinusoidal Pulse Width Modulation) selalu digunakan dalam Power Electronics untuk penukaran DC-AC dan AC-AC.
Skematiknya adalah seperti berikut.
Di bawah adalah cara SPWM Generator berfungsi.
Anda boleh dapatkan programming ini dengan percuma di bawah.
ok thanks. terima kasih.
I’m not teach that part, Mosfet or IGBT circuit. Please search on the internet.
oh okay~i get u mean~may i ask about your circuit process question ?? i have read your programming code about the OUT= 0 or 1 something..mean that u without using BJT or MosfET or IGBT transistor to keep switching ON/OFF in every period produce SPWM right. So in your case ..may i have your teach and guide ??…if using your spwm look like …how to i convert into Sine wave??….must add transistor ???..
i also got build my own circuit but i using H-bridge concept .i havent count the pulse width period to make same as your simulation.
But your one is look good … so may i have your kindly guide ^^ I wait for u Reply ^^ terima kasih…
beginner, depends how your simulation looks like. Can’t put RC filter, normally feeds this signal to Mosfet or IGBT to produce AC Sine Wave.
shahrul may i ask some this circuit information ?? this spwm only got positive cycle??????how about negative cycle ??????????if i use this similiar circuit and code……..could i put RC filter to generate the AC sine wave????wait for u reply ^^ thank for u sharing those knowledge
