摘要： A temperature-controlled solar power inverter is described herein. The solar power inverter includes multiple components (for example, a power transistor, a control board, or a heat sink). The temperature of a component may rise due to heat generated by the component or heat absorbed from other components. The solar power inverter also includes a temperature sensor configured to measure a temperature at a location proximate to the component and a cooling device configured to cool the component. The solar power inverter also includes a controller coupled to the temperature sensor and the cooling device. The controller is programmed to receive the temperature from the temperature sensor and control the cooling device based upon the temperature and a temperature setpoint of the component. The temperature setpoint is based upon 1) a component initial temperature, 2) a temperature excursion limit of the component, and 3) an absolute temperature limit of the component.
