| Abstract: | A 50 Hz sine invertor,in which no power frequency transformer is equipped, therefore it is light and handy. The magnetic bias suppression circuit and the combined over current protection circuit,etc. are available. |
| |
| Keywords: | invertor PWM magnetic bias suppression over current protection |
