Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to photovoltaic capacitors. Background technique [0002] Due to the high operating frequency of photovoltaic capacitors, large ripples and harmonic currents are generated, and the capacitors generate serious heat. At the same time, photovoltaic equipment is used in harsh environmental conditions, and has been working in high temperature and high humidity for a long time, so the requirements for capacitors are more stringent. Therefore, in order to be able to be used under high temperature and high humidity conditions, it must have the characteristics of large overcurrent capability, high withstand voltage, and long life, so as to effectively save costs. Contents of the invention [0003] In order to overcome the above-mentioned problems existing in the photovoltaic capacitor, the present invention provides a photovoltaic capacitor. [0004] The technical scheme adopted by the...
