AI Technical Summary
Technical Problem
In existing hardware-in-the-loop simulation test systems, isolation devices and isolated power supplies are required during signal conditioning, resulting in high costs.
Method used
A digital output circuit is adopted, including a driver module, a charge pump module, and an output module. The driver module generates a signal, the charge pump module provides a feedback signal, and the output module generates the final output signal, thereby achieving signal conditioning and avoiding the use of isolation devices and isolated power supplies.
Benefits of technology
Signal conditioning was achieved without increasing circuit space and cost, thus reducing the cost of the test system.
