Find a downloadable version of this story in pdf format at the end of the story. Boost power converters have been widely used for Power Factor Correction (PFC) in ac-dc conversions [1] and for power ...
A new type of power-conversion topologies known as "sine amplitude converters" is the driving force behind the high performance achieved by Vicor's line of voltage transformation modules (VTMs). The ...
Sunpower’s DAP-04 DALI to PWM converter is designed to provide DALI control in LED lighting applications. The DAP-04 has a DALI input that can accept data from a remote IEC62386-101, 102 or 207 ...
The most common switching-power topology is a buck converter, which efficiently transforms high voltages to low voltages. Figure 1 shows a typical buck converter in which the N-channel MOSFET, Q 1, ...
A current sensor with PWM output is a very useful type of device. Traditionally, the device can serve in a digital application where the host microcontroller can determine the ratio of the on-time to ...
In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...
Once more opto-isolators are to be seen in Wonderland. The aim was to see if the faster photodiode types can operate quickly in common collector mode. They consist of an infra-red led and a fast npn ...
The AR35S18E is a digitally coded conversion IP that translates stereo 16-24bit pulse-code modulated (PCM) input data into pulse-width modulated (PWM) ...
