dsPIC30F Family Reference Manual DS70062D 2005: The motor control PWM (MCPWM) module simplifies the task of generating multiple, synchronized pulse width modulated outputs. In particular, the ...

You could use a variable resistor, but with large currents you would need a very large resistance. Also, the resistor would be wasting a lot of energy as heat at low speeds. If you could connect a DC ...

The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...
