Abstract (en)

A circuit element (10) comprises a first lead wire (12); a second lead wire (14); a third lead wire (16); first and second rectifying elements (D1, D2) which are connected in series in a forward direction between the first lead wire (12) and the second lead wire (14); and a load (20) which is connected between the third lead wire (16) and a connection point (18) between the first and second rectifying elements (D1, D2). V1 ≥ V2 over an entire operating period provided that V1 represents an electric potential of the first lead wire (12) and V2 represents an electric potential of the second lead wire (14). V2 ≤ V3 ≤ V1 in a period in which a current is blocked and does not flow into the load (20), provided that V3 represents an electric potential of the connection point (18). <IMAGE>
