    Egzoset's Univ. 2-Phase 4-Poles IH WorkCoils Assy - 16 mm Aper. - PCBoard Placement of Ti TPA3255

    Egzoset's Universal 2-Phase 4-Poles IH WorkCoils Assembly - 16 mm Aperture - PCBoard Placement of Ti TPA3255 (up to 4 chips) Or... How much is too much??! ...
  2. Egzoset's Univ. 2-Phase 4-Poles IH WorkCoils & LED Illum. Assy - 16 mm Aper. - 2 x Ti TPA3255

    Egzoset's Univ. 2-Phase 4-Poles IH WorkCoils & LED Illum. Assy - 16 mm Aper. - 2 x Ti TPA3255

    Power density ain't a pressing concern anymore, obviously. Each of the 2 chips is rated 300 + 300 Watts if hard-wired for "mono" audio, e.g. possibly the 20 Hz to 48 KHz range since Hi-Fi "Digital Audio" is also covered... Mono only requires 1 "RF Choke" per twin-coils duo (or phase)...
  3. Egzoset's Univ. 2-Phase 4-Poles IH WorkCoils Assy - 16 mm Aper. - 2 x ST Micro TDA7498 (up to 400 W)

    Egzoset's Univ. 2-Phase 4-Poles IH WorkCoils Assy - 16 mm Aper. - 2 x ST Micro TDA7498 (up to 400 W)

    Using a pair of ST Micro TDA7498 chips the total admissible output power should in principle reach up to 400 Watts and yet even leave free PCBoard space for additional/optional electronics, if necessary...
  4. Egzoset's Universal IH WorkCoils Assembly - 16 mm (dia.) IH Aperture - Flux Return Paths

    Egzoset's Universal IH WorkCoils Assembly - 16 mm (dia.) IH Aperture - Flux Return Paths

    Dated (2020-Oct-5).
  5. 4-Poles IH Assembly with 16 mm (dia.) Aperture fits inside 50 square mm PCB Layout

    4-Poles IH Assembly with 16 mm (dia.) Aperture fits inside 50 square mm PCB Layout

    Evaluated dimensions: 5 x 5 x 1 cm, with 5/8" (dia.) IH Aperture.
  6. 2-Phase 4-Poles 16 mm Aperture - Complementary Clamshell Profile(s)

    2-Phase 4-Poles 16 mm Aperture - Complementary Clamshell Profile(s)

    Multi-Mode (Universal) IH WorkCoil(s) assembly concept.
  7. RF-Choking Ballun combined to 2nd Magnetic Circuit splitting through 2 Half-Toroïd paths

    RF-Choking Ballun combined to 2nd Magnetic Circuit splitting through 2 Half-Toroïd paths

    Much like the filename says, except for my particular use there can't be any obstruction in the center. See next picture post to gather why...

  9. 3-Phase Planar (10 mm flat) IH-Driving

    3-Phase Planar (10 mm flat) IH-Driving

    That's about the parts count for a "Half-Bridge" power stage feeding some yet-to-define 3-Phase stepper-like IH WorkLoad, properly compensated by using 3 RC "Snubber" circuits (as an EMi-wise addition).
  10. 3-Phase 9-Poles IH Injection Assembly - Interconnections Puzzle

    3-Phase 9-Poles IH Injection Assembly - Interconnections Puzzle

    Actually this present post continues a topic initially illustrated 5 years ago, it's about evaluating available space for more eventual IH WorkCoil components but not only: https://www.autoflower.net/forums/media/lavawand-capsule-mating-joint.323/ LavaWand Capsule - Mating Joint (2015-May-14)
  11. Magnetic Flux - Open (selenoïd coil) vs Contained (stepper motor)

    Magnetic Flux - Open (selenoïd coil) vs Contained (stepper motor)

    It's about straight cylindrical "air-core" selenoïds and their implicit impossibility to "close" the magnetic circuit between 2 ends or poles which in stepper motors are forced to face each other in order to maximize mechanical torque, thanks to flux-concentrating material, etc.

    Old Reviews DIY for vaporism, possibly e-Cigs (vaping) too.

    Salutations everyone, Lets start with the bar set high, for example i found this video earlier in the summer: YouTube: Induction Heating Titanium Nail (2016-Jun-18) Good day, have fun!! :peace:
