The increasing acceptance of Class D amplifiers has helped them gain market share from their linear Class AB brethren. That acceptance is no surprise; the advantages of Class D amplifiers are legion, ...

Simplicity and low cost sustain the popularity of passive PWM DAC ripple filters despite their limitations. One of these limitations is a high output impedance caused by the series sum of filter ...

Circuit VR is where we talk about a circuit and examine how it works in simulation with LT Spice. This time we are looking at a common low-frequency oscillator known as the Wien bridge oscillator.

There comes a time in every electronic designer’s life when, whether they know it or not, they need an analog filter in their design. If you’re coming from a digital background, where everything is ...

This analytical and graphical technique allows engineers to determine, in closed form, the output of an RC filter driven by a PWM pulse train. It is based on the principle that current and voltage ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

The LR2 line reactor series adds seven new frame sizes to match all GS, DURApulse, and WEG drives. The LR2 Series can also be used with a variety of other variable frequency drives (VFD) ...

Passive circuits for power factor correction (PFC) are simple, reliable, robust, and they don't generate EMI [1-4]. Plus, they offer a low-cost alternative for complying with harmonic current limit ...
