Texas Instruments introduced the industry’s first 70-W brushless DC (BLDC) motor drivers to provide code-free, sensorless trapezoidal, and field-oriented control (FOC). The devices enable engineers to spin a BLDC motor in less than 10 minutes – eliminating months of design time for engineers designing a wide variety of industrial systems such as major and small […]
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 […]
