<p>PURPOSE: An inverter is provided to supply the electricity of DC power to an alternating voltage wiring net by using an asymmetric bridge circuit having two or more second switches. CONSTITUTION: An inverter uses an asymmetric bridge circuit. The inverter supplies the electricity of DC(Direct Current) power including a PVG(Photovoltaic Generator) to an alternating voltage wiring net(N). The asymmetric bridge circuit comprises low-speed switches(S1,S2) and high-speed switches(S3,S4). The low-speed switches having the same temperature stability are used to a wiring net frequency. The high-speed switches having steeper switch inclination and higher temperature stability are used to a higher clock frequency. The high-speed switches are spatially separated from the low-speed switches.</p> |
