Hi Folks:
I have two Sharper Image Ionic Breeze units. These worked good
when they worked. One broke about a year after I bought it, the second
broke just recently. Actually, they both seem to be making high
voltage, but now neither are moving air. I suspect the rectifier
diodes in the transformers are shorted. They both just hiss. The last
working unit hissed and pumped air, but now it just hisses, like the
other one. I'm hunting for a supplier for a replacement transformer.
Also, is it me or do these things suck when it comes to reliability?
;-) I did run them 24/7.

Thanks Folks!
Harry

I'd try a microwave oven diode, they're cheap, and most are rated for
500mA, if you're exceeding that in an ionizer then you've got some
serious problems.

Does it not sound like a low voltage power supply if he has a fan
problem? If its a DC fan that's not turning, (look on the fan for its
voltage), it maybe just simple 1 to 3 amp rectifiers at 600/1000piv.
Now, it might be possible that the fan sucked in so much crap that
its froze up. You might be able to clean it out and revive it if that
was the case. You need to determine if there is voltage at the
fan and if the fan is full of crud.

They don't use any fans. It's all "Corona Wind".

If the diodes are shorted, I would think a 10KV would
work. Ionizers usually run up over 5KV. DC Ionic breezes
can be measured. A Neon lamp with a dual electrode wand
flashes as electrons are collected. A digital DC voltmeter
can also be used. Hold one probe with one hand, hold
the other NEAR but not touching the device. The voltage
will increase as charges are collected. If it putting out AC,
there will be no charge collected. I've had trouble lately
looking for suppliers of suitable transformers. Ozone
generators use AC, not DC.

They may need to be fast recovery/high frequency diodes.

Hi! Thanks for the reply! I'd think one of those diode are too slow
and leaky to rectify this 10kHz or so. Probably too-low voltage, too.
Maybe a Television flyback diode?

Hi! The ion breeze has no fan. I think just the DC ion movement pulls
air through it.

Yes, a TV or monitor flyback rectifier, if you can find one.

However, I assume there are high frequency microwave oven HV rectifiers - used
in inverter-type microwave oven power supplies.

SG rectifiers - used in inverter-type microwave oven power supplies.

Most ion generators have the usual Cockcroft-Walton voltage multiplier
which boosts the input voltage into the 3 to 4 kilo volt range. Thus
the rectifiers used don't need to support the whole voltage but only
that fraction in each step up. It is especially cost effective to use
lower voltage rectifiers and capacitors. Comparatively speaking a high
voltage rectifier and capacitor are rather expensive and relatively
rare components.

You know, actually I've used microwave oven diodes with high frequency
and amazingly enough they worked great. I built a replacement doubler
for an old Electrohome vector monitor, actually I've made several of
them now using a 10kV capacitor and a pair of microwave diodes, IIRC it
runs about 20 KHz. Those diodes are rated 12 KV and seem to be very
robust, only a few dollars too.
