Photovoltaic (PV) inverter plays a crucial role in PV power generation. For high-power PV inverter, its heat loss accounts for about 2% of the total power. If the large amount of heat generated during the operation of the inverter is not dissipated in time, excessive temperature rise will reduce the safety of the devices. This.
Heat sink with a higher CHP reduces the die temperature more as the material have a low thermal resistance and high thermal capacitance. The CHP describes how much thermal capacity is available within the early.
