Power Electronics Thesis: Grid-Synchronized Single Phase Inverter

[mvocray]

Hi to all! I'm starting with my thesis po. The plan is to make an efficient single-phase inverter using quasi-square SPWM that synchronizes itself to the grid. Tanong ko lang po kung meron ditong naka-experience nang gumawa ng similar project? The focus of my project is the line synchronization pero important din po yung ibang specs. I'll be starting from scratch meaning wala pa po talaga akong experience gumawa ng ganitong circuit pero I've read the basic theories and topologies. Application po sana nito sa solar, so I'm really interested with the project although di ako expert sa field.

Also, may masusuggest po ba kayong readings, books, ebooks, etc.? Anything will do. Thank you po.

Maganda objective mo kya lang medyo mahirap. Cge try ko rin assist kung may makikita me details.

"Grid-Synchronized" -> medyo ok pa..
"Grid-Tied" --> mahirap (pero meron ng mga products na ganito)..

Excellent topic for Thesis.. sa tingin ko kumukuha ka ng masteral.. This project is high-end which I think will involve motors and drives.. For prototyping, the PIC17C42, PIC18F6520 or dsPICxx MCU's are excellent choice for your application otherwise, you may want to use this MC68F333 32bit mama-monster in your project also possible to generate complex SPWM waveform.. possible to code in assembly your SPWM algorithm but it is indeed difficult..

Using sinusoidally modulated (SPWM) inverter the supply frequency to the motor can be easily adjusted for variable speed. This type of control is widely referred to variable voltage to frequency ( v/f )

Hindi ko gaanong alam kung ano itong single-phase inverter using quasi-square SPWM that synchronizes itself to the grid pero parang maganda and tunog. Ano po ba ito? San po ba ito magagamit?

Kung sinewave inverter using PWM, applicable siguro iyong mga design ng Class D amplifiers.
