CAPACITIVE DRIVEN NORMAL RELAY EMULATOR USING VOLTAGE BOOST

摘要

A normal relay emulator is described. The normal relay emulator may include a trigger circuit configured to detect a condition on a first power rail, the first power rail having a first voltage supply level. A boost converter electrically coupled to the first power rail and configured to boost the first voltage supply level to a second, higher, voltage supply level is provided. A bi-stable relay having a first terminal and a second terminal and an actuator electrically coupled to the boost converter and communicatively coupled to the trigger circuit is also provided. The actuator may be configured to energize the bi-stable relay using the second voltage supply level such that electrical contact between the first terminal and the second terminal changes between a first state and a second state based on the trigger circuit detecting the condition.

1. A normal relay emulator comprising:
a trigger circuit configured to detect a condition on a first power rail, the first power rail having a first voltage supply level; a boost converter electrically coupled to the first power rail and configured to boost the first voltage supply level to a second voltage supply level, the second voltage supply level higher than the first voltage supply level; a bi-stable relay having a first terminal and a second terminal; and an actuator electrically coupled to the boost converter and communicatively coupled to the trigger circuit, the actuator configured to energize the bi-stable relay using the second voltage supply level such that electrical contact between the first terminal and the second terminal changes between a first state and a second state based on the trigger circuit detecting the condition.
