TRANSFORMER-LESS TYPE INVERTER CAPABLE OF MINIATURIZING AN INVERTER BY REMOVING A TRANSFORMER

摘要

PURPOSE: A transformer-less type inverter is provided to simplify a structure by generating an AC through switching electric potential difference which is a DC voltage level.;CONSTITUTION: A first and a second rectifiers(121,122) generates a first and a second voltage by rectifying a commercial AC, respectively. A first and a second output port respectively output the first and the second voltage. A resistor(170) is arranged between the first and the second output port. A first switch(160) is arranged between the output terminal of the first voltage and the first output port. A second switch(190) is arranged between the output terminal of the second voltage and the second output port. A switching controller(140) turns on/off the first and the second switch, alternately.;COPYRIGHT KIPO 2010
