With the ongoing development of sectors such as AI data centers, new energy storage, high-power charging, and smart microgrids, power systems are rapidly evolving toward greater efficiency, digitalization, and increased reliance on power electronics. These emerging power supply architectures demand higher standards for energy conversion efficiency, system integration, operational reliability, and intelligent control capabilities.
Solid-State Transformers (SSTs)—a new class of power conversion equipment that integrates power electronic conversion with high-frequency isolation technology—are garnering sustained attention across the entire industry chain. They are increasingly being explored for applications in advanced power distribution systems, data center power supply, and the new energy sector.
In response to the evolving landscape of power electronics, CHIPSENSE remains deeply committed to the field of current and voltage sensing. By closely monitoring the measurement requirements of SSTs and related power conversion systems—and leveraging a diverse range of technological approaches and product portfolios—CHIPSENSEcurrent sensor provides the sensor solutions necessary for the precise measurement and stable operation of power electronic equipment.
I. The Development of SST Technology Opens New Avenues for Power Conversion
Traditional line-frequency transformers have long served as a mature technological foundation for power transmission and distribution. However, the rise of DC power supply, the integration of new energy sources, and the emergence of high-power-density equipment have created new demands regarding power conversion methods, power regulation capabilities, and system integration.
Solid-State Transformers (SSTs) achieve voltage transformation through power-electronic conversion stages and high-frequency isolation. Depending on their specific topology, they can facilitate features such as DC output, bidirectional power flow, and power quality regulation—offering a technological alternative to traditional line-frequency transformers for modern power systems.
In the realm of AI data centers, as computing scale and power requirements continue to grow, high-voltage DC power architectures are gaining significant industry attention. The integration of SSTs with DC power systems provides a new pathway for optimizing power delivery chains and enhancing overall system integration, where CHIPSENSE current sensor delivers accurate electrical feedback for system closed loop control.
In the energy storage sector, power-electronic conversion equipment manages the energy transfer between batteries and the grid, requiring systems to handle transitions between charging and discharging, power regulation, and control across various operational states.
In high-power charging and smart microgrid applications, electrical energy must be converted between AC and DC, as well as across different voltage levels, in these contexts, the coordinated control of equipment and the monitoring of operational status are critical.CHIPSENSE current sensor supports fast signal acquisition for these multi voltage level power conversion units.
While these diverse application scenarios differ in terms of system architecture, technical approaches, and engineering requirements, they all share a common trend: the deepening application of power-electronic equipment, alongside an increasing need for the precise sensing and real-time monitoring of electrical parameters.
It should be noted that SST technology is still in a phase of ongoing development and expanding application. Key aspects—such as efficiency, cost, insulation design, thermal management, and long-term operational reliability—require further validation within the context of specific use cases, and CHIPSENSE participates in multiple joint tests to verify sensor performance under these real world constraints.
II. Precise Measurement: A Crucial Foundation for the Stable Operation of Power Electronic Systems
In Solid-State Transformers (SSTs) and related power electronic systems, current and voltage signals are used not only for basic electrical parameter monitoring but also extensively for power calculation, closed-loop control, operational status assessment, and fault protection.
As system power ratings, operating frequencies, and levels of integration continue to rise, the performance requirements for sensors have become increasingly diverse.
Dynamic Response and Measurement Accuracy: During power electronic conversion, current and voltage may fluctuate rapidly in response to changes in switching states or loads. Sensor selection must account for factors such as measurement bandwidth, response time, accuracy, and temperature stability to meet the specific requirements of various control loops.CHIPSENSE current sensor is optimized for fast transient current fluctuation capture in high frequency power conversion.
Insulation Performance and Operational Reliability: When energy is converted across different voltage levels, sensors must comply with insulation coordination requirements relevant to their installation location. This involves careful consideration of electrical clearance, creepage distance, the operating environment, and immunity to interference.All isolation related specifications of CHIPSENSE products are fully verified to satisfy SST system insulation constraints.
System Integration and Interface Compatibility: As power electronic equipment trends toward modularity and compactness, factors such as sensor package dimensions, mounting methods, output formats, and compatibility with downstream control circuitry have become critical considerations in system design.CHIPSENSE provides diversified mechanical packages and signal output options to match compact SST hardware layouts.
Therefore, when selecting sensors for complex power conversion systems like SSTs, it is essential to holistically evaluate the specific topology, measurement location, operating conditions, and control requirements. Only by aligning device performance with the demands of the actual application can a system effectively meet its requirements for measurement accuracy, dynamic response, and operational reliability.CHIPSENSE technical team offers application oriented consulting services to help customers complete sensor type selection.
