Title: Power converter and power conditioner
Inventor: MABUCHI MASAO
IPC: H02J3/38
Filed: 2010-03-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a power converter that enhances conversion efficiency from a DC power to an AC power.  <P>SOLUTION: A first chopper circuit 5 chops a DC voltage from a solar cell panel 1 at a system frequency to produce a first square-wave voltage string whose voltage level changes onto a positive side. A second chopper circuit 6 chops the first square-wave voltage string at a frequency double the system frequency to produce a second square-wave voltage string whose voltage level changes onto a negative side and adds both the square-wave voltage strings to produce a third square-wave voltage string that alternately changes in a sine-wave manner on positive and negative sides. A third chopper circuit 7 performs charge and discharge by chopping the third square-wave voltage string at a third frequency defined by timing corresponding to a positive or a negative of a difference between the third square-wave voltage string and a sine-wave voltage, and PWM control is performed for outputs of the charge and discharge at a PWM frequency so that the difference is corrected, thereby producing a sine-wave voltage that continuously changes on the positive and negative sides. Further, a spike noise of an output voltage is suppressed.  <P>COPYRIGHT: (C)2011,JPO&INPIT
