A Relay Drive Circuit for a Safe Operation Order

概要

論文の詳細を見る
A fail-safe relay drive circuit, which outputs only under no-malfunction situations and which outputs to two relays with some time difference to avoid the common mode failure of the welding of contacts, is proposed. The output and the correct safe timing of driving/de-driving the relays are achieved by CMOS inverters and linear regulators, as well as the relay drive circuit with constant output voltage by a transformer.
