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 this post I will try to gain some insight into the electronics of a cheap PWM Power MOSFET Module. The module under the spotlight is the pretty common FR120N MOSFET Control Module which is a simple ...

The MSK 4225 is a 75 V, 20 A MOSFET H-bridge PWM motor driver or amplifier. This device is suitable for DC brushed motor control or Class D switchmode amplification. All of the drive/control circuitry ...

Most microcontrollers have a pulse-width modulator (PWM) output that can effectively drive variable output loads such as proportional solenoid valves, motors, or light dimmers. You control these loads ...

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 ...

Sometimes it’s necessary to drive a resistive load such as an incandescent bulb or heating element from a DC voltage that’s higher than the nominal load voltage. An example would be driving a 6.3-V, ...
