Digital Power Electronics - Worldwide Forecasts

Digital Power Electronics: Worldwide Forecasts, Third Edition

The digital power landscape is undergoing rapid change. Adaptive controllers, parameter estimation and sophisticated control algorithms have become much more economically reasonable to implement in a variety of systems. But there is still a “perceived expense” of going digital, compared to using similar bandwidth analog components.

Although digital solutions are still primarily being used in high-performance applications, the pervasive emphasis on energy efficiency is pushing digital from high-end-only into the mainstream. Digital control is now implemented in just about all application segments, from catalog power supplies to power supplies used in medical, solid-state lighting and consumer devices. In some applications, digital penetration is already exceeding 50%.

Major shifts in market share of each IC type have been occurring since 2005, and these are expected to continue through 2014. During the “emerging years” of digital (2005-2008), sales were less differentiated between IC types, particularly for ac-dc power supplies and dc-dc modules. Beginning in 2009, however, we expect changes in the market that will alter the mix more quickly through the remainder of the forecast period. These shifts can be analyzed as part of the traditional “Product Life Cycle Curve,” with digital power just entering the “Growth” phase, and Maturity expected around 2014.

The worldwide digital IC market (including controller ICs, converter ICs and system management ICs) is expected to grow from over 5 billion units in 2009 to 12.3 billion units in 2014, a compound annual growth rate of 19.8%. This will be spread out over a diverse market of power supplies, including external ac-dc and embedded ac-dc power supplies, dc-dc modules, embedded dc-dc converters, telecom rectifiers and external dc-dc, lighting ballasts and inverters. Price declines will only begin to slow by 2013, so dollar sales will experience a healthy growth rate of just over 29% up to this point.

With this broader implementation, along with expanded digital IC functionality, digital power management and control is entering a long-awaited “mainstream adoption” period. The next ten years will see increased use of digital control, as applications demand power functions for which digital is particularly suited.
