Fuel cell provider Bloom Energy has given its Energy Servers the ability to follow loads, so they can adjust to variable demand and supply in microgrids and utilities. The 'Be Flexible' offering works ...

Although variable DC power supplies might appear to be relatively simple devices common to every engineer’s benchtop, they are actually sophisticated instruments. They must reliably deliver voltage ...

Many microcontrollers feature a pulse-width-modulated (PWM) output that can be low-pass filtered to produce a variable dc voltage. Without additional circuitry, however, this technique is limited to ...
