Today’s VFDs rely on fast-switching IGBTs that can generate steep dv/dt levels, voltage reflections across long motor cables, ...
It’s just a fact, I’m curiously fond of topologies that combine PWM switching and filtering circuitry with power handling devices like adjustable voltage regulator chips. This scheme makes ...
Pulse width modulation (PWM) control, which uses variable-width digital pulses to represent the amplitude of an analog waveform, has been around for decades. The first specialized PWM IC dates back to ...
International Rectifier introduced a Class D audio chipset comprising the IRS20965 digital audio driver IC with protected Pulse Width Modulation (PWM) switching and a full complement of audio MOSFETs ...
Tailored to medium and high-power SMPS applications, the L6591 is allegedly the first integrated controller optimized for zero-voltage switching asymmetrical half-bridge converters. The device, ...
Continental has been granted a patent for a method of switching electronic components using pulse-width modulation signals. The method controls output signals through control signals, adjusting them ...
Webasto has been granted a patent for a method to check semiconductor switch faults. By evaluating current measurements or voltage pulses based on duty cycle, faults like short circuits or open ...
