The power stage solution for motor control, high-voltage charging, and DC/DC conversion offers safety features, diagnostic tools, and adaptability to various applications.
The TIDA-020030 reference design from Texas Instruments provides design engineers with a power stage solution for developing power control systems in various applications. This design suits inverter and motor control development, particularly for hybrid and electric vehicle (HEV/EV) traction inverters. With its current handling capabilities and protection features, engineers can create reliable systems that meet the performance requirements of motor control applications.
Another application is in the development of onboard and wireless charging systems. The reference design supports high-voltage and high-current loads, with overcurrent and short-circuit protections, making it suitable for charging systems where safety is essential. The design also supports DC/DC converters used in power distribution systems. Monitoring DC bus voltage and providing fault control ensures proper operation of power conversion systems in various environments.
The reference design is customizable for different applications. It can be adapted for gasoline and diesel engine platforms, motor control systems, and other power electronics systems, offering flexibility and scalability for various power control needs.
Engineers can also utilize the protection and safety features built into the design. The TIDA-020030 includes shoot-through protection, overcurrent and short-circuit protection, and temperature monitoring through thermal diodes, helping ensure compliance with safety standards in power systems. These features are important for applications in automotive, industrial, and other high-power environments where system reliability is necessary.
The design integrates diagnostic and system monitoring features. Engineers can validate and monitor system performance in real-time with fault signal injection, PWM gate-signal monitoring, and a 12-bit ADC for temperature sensing. This enables quick fault detection and optimization of system functionality.
Additionally, the TIDA-020030 offers an input voltage range of 4.5 V to 65 V DC and provides up to 180 mA of output current, making it adaptable to various applications with different voltage requirements. The power stage also includes isolated gate drivers, redundant circuits, and fault detection mechanisms, allowing for integration into complex power systems.
The design includes the LM5180-Q1 flyback converter, which works with an input voltage range from 4.5 V to 70 V. It controls the output voltage by measuring it from the primary side, so it doesn’t need extra parts like an opto-coupler or a third winding on the transformer. It also has an isolated amplifier that separates the input and output by a barrier that blocks magnetic interference. This barrier ensures safety with up to 7 kV protection and meets safety standards like VDE V 0884-11 and UL1577.
