Interleaved PWM with discontinuous space-vector modulation
Interleaved PWM with discontinuous space-vector modulation

... Putting modules in parallel, however, is not risk free. One of the major concerns for the parallel operation of a three-phase system is the crosscoupling between modules because when these modules are connected to the same dc bus and a common source/load, extra current conduction paths are formed. T ...

Speaker motors and passive crossover filters
Speaker motors and passive crossover filters

... Most speakers used for high fidelity purpose split the audio band into more than one region. This requires a series of filters to split the band, and the filter is often one using passive reactive devices connected in line with the speaker circuit. The low impedance nature of the linear motor requir ...

... Note 5: Note that the LVDS CWD LO clocks are DC-coupled. This is to ensure immediate synchronization when the clock is first turned on. An AC-coupled LO is problematic in that the RC time constant associated with the coupling capacitors and the input impedance of the pin causes there to be a period ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
