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 ...

H Bridge configuration is commonly used in electrical applications where the load needs to be driven in either direction. A typical H-Bridge structure is shown below; The current flows through the ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...

Allegro MicroSystems Europe has unveiled a three-phase brushless BLDC motor controller for use with N-channel external power MOSFETs. The AMT49413 incorporates much of the circuitry required to design ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

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 ...

For IGBTs, the on-state voltage drop is a critical specification to consider. This drop includes both the diode drop across ...

Tutorial on ac-motor control based on Clarke and Park transforms. Concepts are presented in stages from top-level through deeper levels of detail. Regardless of their primary field, sooner or later, ...
