Design of spwm inverter - ICs and SG3525

[sambkn2bhu]

hii.. m trying to design SPWM inverter. For that i was looking for some spwm ICs and i came across SG3525.. but is it spwm ic or just pwm ic for spms n dc-dc conversion. bcoz after reading its datasheet m having an illusion of this being a pwm ic only.. not an spwm.. pls pls help me with this..

thanx...

The SG3525 is simply a PWM chip, not SPWM.

I'm not aware of single chip sine PWM solutions (besides uP/DSP/FPGA). Are there any?

Re: spwm inverter

so how can i generate my sine wave 50hz n tri. wave 20Khz to generate my spwm pulses... i found xr2206 to be a good solution for this.. is it ?

Re: spwm inverter

TL494 is commonly used for sine wave inverters, its a modified sine wave generator. Another way around is to determine switching pattern from matlab
and generate it via cheap microcontroller.

pls can you help with 12vdc to ac inverter circuit and schematic diagram
