Digital Power Overview<br />
Digital control of power conversion systems<br />
results in lower overall cost due to<br />
the consolidation of functions into a single<br />
programmable controller in place of<br />
dedicated discrete components. A single<br />
TMS320C2000 digital signal controller<br />
can provide full loop control at over<br />
2-MHz switching frequencies or control<br />
multiple output levels and simplify the<br />
sequencing of multiple supplies through<br />
software rather than dedicated<br />
components. A software-based solution<br />
enables intelligent monitoring of load<br />
conditions in real time and can lead to<br />
improved system reliability, efficiency<br />
and operating costs.<br />
C2000 digital signal controllers provide<br />
both isolated and non-isolated solutions<br />
from AC-line to point-of-load and are<br />
suitable for applications such as uninterruptible<br />
power supplies, servers, telecommunications,<br />
solar inverters and<br />
industrial equipment. The C2000<br />
controllers connect easily with TI’s<br />
UCD7000 series of digital power drivers<br />
to interface with the actual power stage.<br />
TI provides a free library of power conversion<br />
software systems that are tailored<br />
to different power conversion<br />
topologies, including DC/DC buck and<br />
phase-shifted full-bridge, along with<br />
power factor correction modules. These<br />
can be evaluated in hardware using an<br />
F2808 eZdsp along with our low-cost<br />
PFC and DC-DC adapter boards.<br />
