4 High-Voltage Opto Isolator Applications

Miniature high-voltage opto isolators may be small, but they play a big role in important technologies we use daily. Opto isolators provide electrical isolation and facilitate communication between components without direct electrical contact. They are crucial for safely controlling and distributing power across various applications, from cars to pacemakers. We’ll explain four high-voltage opto isolator applications.


The Automotive Industry

Miniature high-voltage opto isolators are hard at work inside automobiles. They provide electrical isolation and noise reduction in critical systems. Opto isolators prevent electrical noise interference for engine control modules, anti-lock brake systems, and other automotive electronics while safely controlling currents. These systems can operate despite the electrical noise from alternators, ignition systems, and other vehicle components.


The Medical Industry

Pacemakers, defibrillators, and other life-saving medical devices utilize electrical currents, so opto isolators play an essential role in patient safety. By isolating the electrical current, high-voltage opto isolators allow the device to separate the patient’s natural electrical current from the equipment's power.


Isolating an electrical source protects the patient from the risk of electrical shock and allows the device to deliver the electrical pulses needed for treatment. Opto isolation is necessary to ensure no unintended currents pass through the patient’s body.


Telecommunications

Another high-voltage opto isolator application lies within telecommunication systems. It prevents interference on calls in mobile networks and other communication systems. Without it, issues like voltage surges or ground loops could interfere with the quality of a call or data transmission.


Industrial Fields

Opto isolators enable operators of industrial equipment and high-power systems to control processes with output voltages. By isolating control signals from high-power elements, miniature opto isolators allow a small input signal to trigger the switching of much higher voltages in motors, power converters, and industrial machinery. This makes it possible to build smaller, safer control systems that can withstand extremely high voltages in the larger system they manage.
