DC-AC POWER CONVERTING APPARATUS AND SOLAR POWER SUPPLYING APPARATUS INCLUDING THE SAME

摘要

There is provided a DC-AC power converting apparatus that does not employ a capacitor for removing a ripple in an input terminal by charging or supplementing power according to a difference in power levels between power output by a solar cell and system instantaneous power or employs a capacitor having a low capacity, and a solar power supplying apparatus including the same. The DC-AC power converting apparatus includes: a DC-AC power converting unit that switches DC power and converts the DC power into AC power; and a charging and discharging unit that charges surplus power generated in a switching operation when a power level of the DC power is higher than a power level of the AC power and discharges the charged power through the switching operation when the power level of the DC power is lower than the power level of the AC power
