I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

An H-bridge (full-bridge) driver is quite popular in driving loads such as brushed DC motors and it is widely used in robotics and industry. The main advantages of using an H-bridge driver are high ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...
