| 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. |
| Key words: invertor PWM magnetic bias suppression over-current protection |
