Transformers for ultrasonic sensing applications
Ultrasonic sensing is used in various automotive and industrial applications ranging from liquid level sensing to robot obstacle detection and automated parking assistance. Transformer-based designs can produce highly accurate solutions with maximum ranging distances. This FAQ will review several applications for ultrasonic sensing, compare the capabilities of transformer drive with direct drive solutions, and then […]
Gate drive transformer specifications and applications
Gate drive transformers are often a good solution for providing galvanic isolation in high-voltage and high-frequency applications where fast and accurate signal timing is critical. A gate drive transformer is optimized to handle fast-rising and fast-falling rectangular pulses to turn power switches “on” and “off” in switching power converters. Although many gate drive transformers have […]
