Abstract
There is provided an overvoltage protection circuit including: a comparator configured to compare a DC voltage supplied to a first load by a power generator with a first value set based on an upper limit of an operating voltage of the first load; a storage element configured to be charged with a portion of a current generated by the power generator; and a switch configured to change a flow of the current so that: when the DC voltage is higher than the first value, the portion of the current is supplied to the storage element and a second load coupled to the storage element in parallel, and when the DC voltage is less than or equal to the first value, the storage element supplies the second load with power.
