Why Are Wide-range Voltage Regulators With Overvoltage And Undervoltage Protection More Expensive?

The development of the wide range stabilizer for ac involves not only conventional voltage regulation control loops but also the development and testing of additional protection algorithms. Furthermore, extensive verification is required during the production phase, focusing on performance boundaries related to overvoltage and undervoltage.

Designs with overvoltage and undervoltage protection typically require more sophisticated voltage detection and protection modules. These modules include precision sensing units for input voltage states, switching components for real-time adjustment, and additional safety disconnect mechanisms. Because these additional circuits must operate under a wider range of input conditions, their selection and layout are more complex than basic voltage regulator circuits, thus placing higher demands on PCB space, electrical isolation, and thermal management.
