Application Fields

• Wind Turbine Control: In the field of wind power generation, the DS200DSPCH1A module can be used in wind turbine control systems. It can precisely process various signals of wind turbines, such as adjusting the blade angle in real time according to signals from wind speed and direction sensors to achieve the best wind energy capture efficiency, while monitoring and regulating parameters such as the output voltage and current of the generator to ensure stable power output.

• Dynamometer Test System: In dynamometer applications, the module can leverage its powerful signal processing capabilities. It can receive signals from various sensors on the dynamometer, including torque sensors and rotational speed sensors, analyze and process these signals, and then precisely control the loading device of the dynamometer to simulate different load conditions, thereby accurately testing and evaluating the performance of the device under test (such as engines and motors).

• Multi-bridge Power Converter Control: For multi-bridge power converters, the DS200DSPCH1A module can provide the required communication bandwidth and computing power to directly control the operation of the power converter. It can precisely control the switching states of each bridge arm to achieve precise regulation of output voltage and current, meeting the power needs of different loads, while also conducting real-time monitoring of the power converter and taking timely protective measures in case of faults such as overcurrent and overvoltage.

• Uninterruptible Power Supply (UPS) System: In a UPS system, the module can be used for monitoring and managing battery status and controlling the inverter. By real-time collecting battery voltage, current, temperature, and other information, it analyzes the remaining battery capacity and health status to ensure timely and stable switching to battery power supply mode when the mains power is interrupted. Meanwhile, it precisely controls the output of the inverter to ensure the stability of the frequency and voltage of the output alternating current, providing a reliable power supply for loads.
