Title: Req: 220 V DC to 220 V AC Inverters. Post by: charudatt on December 14, 2009, 01:14:41 13:14 I am looking for some designs to convert 220 V DC to 220 V AC, any help ?

if u want sine wave out then use PWM wave with H- Bridge and filter with a LC filter........... search this forum and u will find details....... Title: Re: Req: 220 V DC to 220 V AC Inverters. Post by: mjtooba on January 28, 2010, 07:55:52 19:55 take care of RMS and average.
actually sine wave is ideal but if you using cheap square wave , take care of RMS. for resistive load,you must decrease Duty-Cycle or amplitude to gain 220V RMS. |
