What is Digital Power?

Generic Power System Block Diagram

The controller block is what differentiates between a digital

power system and a conventional analog power system

Digital ??

PWM

Sensor(s)

Bandwidth limitations (sampling loop)

PWM frequency and resolution limits

Numerical problems (quantization, rounding,…)

AD / DA boundary (resolution, speed, cost)

CPU performance limitations

Bias supplies, interface requirements

Component drift and aging / unstable

Component tolerances

Hardwired / not flexible

Limited to classical control theory only

Large parts count for complex systems

Insensitive to environment (temp, drift,…)

High reliability

S/w programmable / flexible solution

Precise / predictable behavior

Advanced control possible (non-linear, multi-variable)

Can perform multiple loops and “other” functions

High bandwidth

High resolution

Easy to understand / use

Historically lower cost
