  1. Wireless power transfer - Wikipedia › wiki › Wireless_energy_transfer

    Jun 06, 2021 · Wireless power transfer is a generic term for a number of different technologies for transmitting energy by means of electromagnetic fields. The technologies, listed in the table below, differ in the distance over which they can transfer power efficiently, whether the transmitter must be aimed (directed) at the receiver, and in the type of electromagnetic energy they use: time varying electric ...

  2. Ferrite core - Wikipedia › wiki › Ferrit_core

    It is important to select the right material for the application, as the correct ferrite for a 100 kHz switching supply (high inductance, low loss, low frequency) is quite different from that for an RF transformer or ferrite rod antenna, (high frequency, low loss, but lower inductance), and different again from a suppression ferrite (high loss ...

    May 22, 2021 · I decided to use the ready-made one. The thyristor opening frequency varies from units of hertz to units of kilohertz. Decoupling from the power circuit is not through an optocoupler, but through a transformer. p.s. oscillation frequency only mains frequency 50 Hz. No high frequency fillings are observed.

    May 21, 2021 · In my layman view, SET amplification should only be used band-passed in an active configuration driving "real" horn speakers of very high sensitivity (~100dB or over). Paired with a standmounts (f.e. Leben & SHL5+s) they'll be clipping like crazy and putting out 3 or 10% THD and similar amounts of IMD.
