  "textContent": "A grid interconnection inverter includes: a voltage conversion circuit configured to output an intermediate voltage by raising or lowering an input voltage from a direct current power source; and a waveform conversion circuit configured to convert the intermediate voltage into a alternating current power in a sine waveform shape. The voltage conversion circuit includes: a positive-side circuit arranged on a positive-side line between a positive polarity of the direct current power source and the waveform conversion circuit; and a negative-side circuit arranged on a negative-side line between a negative polarity of the direct current power source and the waveform conversion circuit. The positive-side circuit and the negative-side circuit have circuit configurations symmetric to each other.",
