  "textContent": "This application provides a neutral point clamped inverter and a photovoltaic power supply system. The neutral point clamped inverter may include a power module, a switch module, and a control module. The power module may include a power supply and a first capacitor and a second capacitor that are connected in series and then connected in parallel to two ends of the power supply. The switch module may include a first switch unit, a second switch unit, and a third switch unit. The control module may be separately connected to the first switch unit, the second switch unit, and the third switch unit. The control module may control each of the first switch unit, the second switch unit, and the third switch unit to be turned on or turned off, so that different switch units in the switch module are selected to bear a conduction loss or a switching loss. Based on this application, different switch units may be flexibly selected to bear the conduction loss or the switching loss, to reduce losses of the neutral point clamped inverter in all working conditions, and achieve higher efficiency and high applicability.",
