RESTRAINT

Increasing Raw Material and Component Costs

Rising prices for critical SMPS components like inductors, capacitors, and semiconductor ICs pose a significant restraint on market growth. Between 2021 and 2024, prices for ferrite cores used in transformers rose by 19%, while silicon carbide MOSFETs, commonly found in higher-end SMPS, increased by 24%. Global shortages in microcontrollers and digital signal processors have also led to delays in production cycles, especially for digitally regulated power systems. Additionally, tariffs and trade restrictions between major economies have created supply chain volatility. In some regions, manufacturing lead times for key SMPS components extended from 8 weeks to over 16 weeks in 2023. This has discouraged smaller manufacturers from scaling up and has increased the unit cost of mid- and high-power SMPS by an average of 15% over the past year.

OPPORTUNITY

Expanding Demand in Renewable Energy and EV Infrastructure

There is significant opportunity for digital SMPS in renewable energy systems and electric vehicle infrastructure. Over 1.3 million rooftop solar inverters were deployed in 2023 globally, each requiring precision power control modules rated between 300 W and 1,500 W. Likewise, EV charging infrastructure saw over 600,000 new installations worldwide in 2023, with 35% of these units incorporating advanced digital SMPS modules. Countries like China, Germany, and the United States are offering grants and tax incentives for integrating smart energy systems, fueling demand for embedded SMPS solutions.
