The use of a high-T c YBaCuO superconducting film as a switch element of a rectifier was investigated. It was shown that a film can work as a controlled switch at a frequency up to 20 Hz, at current approximately 4 A and voltage approximately 4 V with current-stimulated quench. Film performance in the switch mode was calculated and theories and experiments were compared. Based on high-T c films it is possible to develop superconducting rectifiers that can work at the temperature of liquid nitrogen.
