Title: Req. help with grid sinchronization of DC/AC inverter Post by: Sun_rise_pt on August 15, 2007, 10:16:11 10:16 Hi friends!
I need a help with a practical methode (schematics) to track the 50Hz line grid and lock my DC to AC converter ( 220V / 1 phase ). Thank you. Title: Re: Req. help with grid sinchronization of DC/AC inverter Post by: sohel on August 15, 2007, 11:08:26 11:08 must be same curve.

I think to need a PLL or similar to track the frequency and phase... I don't have a ideia how the commercial grid tied inverters works t with the synchonization. Then if anybody have a schematics are beautyful. Title: Re: Req. help with grid sinchronization of DC/AC inverter Post by: sohel on August 15, 2007, 04:12:18 16:12 sorry i have no idea about it,

Search FreeScale's site. They have On-Line UPS designed with DSP5680x & CPU12. Register & you can get complete source code & schematics. Both designs include Line-Synchronization using Digital Controllers. reagrds, sam_des Title: Re: Req. help with grid sinchronization of DC/AC inverter Post by: Taner on August 17, 2007, 07:13:57 19:13 Hi,
what kind of synchronization you need, digital or analog PLL. I have a one analog solution for grid synchronization, with one generator and sallen-key low-pass filter, but have a dephasing with grid. :) Title: Re: Req. help with grid sinchronization of DC/AC inverter Post by: Sun_rise_pt on August 18, 2007, 09:55:08 09:55 Hi Taner.
Share this with us, please. Thank you. Title: Re: Req. help with grid sinchronization of DC/AC inverter Post by: Taner on August 22, 2007, 07:10:13 19:10 Hi Friends,
here is a circuit of the grid synchronized generator. Best Regards: Taner :) Title: Re: Req. help with grid sinchronization of DC/AC inverter Post by: Sun_rise_pt on August 23, 2007, 06:39:14 18:39 Thank you Taner.
Are a good help for me! |
