Description

technical field [0001] The invention relates to the field of photovoltaic conversion circuits, in particular to a photovoltaic conversion circuit suitable for fixed and mobile WSN nodes. Background technique [0002] The Internet of Things is to continuously send data to the monitoring center by placing fixed or robotic mobile wireless sensor nodes to monitor various indicators of the research object. Most sensor nodes are powered by dry batteries, but dry batteries have a short service life and need to be replaced frequently. For sensor nodes that have been put into monitoring environments, these later maintenances are time-consuming and labor-intensive. In addition, the chemical substances in dry batteries are not easy to degrade and will also cause great pollution to the environment. Contents of the invention [0003] The purpose of the present invention is to provide a photovoltaic conversion circuit suitable for fixed and mobile WSN nodes, so as to realize the node p...
