Greetings,

I am experimenting with the inverter board from the Panasonic
NN-H665BF microwave oven (part no. F66456G01AP) in an effort
to convert it from constant power to constant voltage and
reduce output noise, ripple, and voltage to 2kV. I have
the schematic for a somewhat similar Panasonic oven, the
NN-G62BH, but there are big differences, especially that
my oven inverter uses only a single IGBT driver, has
no current transformer and uses a very different control
IC.

In a web forum, a poster mentioned having schematics for
these ovens on a 'Panasonic Service Manual CD' but I have
not found any other reference to this online.

Does anyone have a schematic or could point me to a source
(the Panasonic website only shows 'Instruction Manuals'
which are users' guides.)?

Hopefully I can save the many hours required to trace the
PCB. Thanks,

Michael

They don't print schematics for microwaves. It's because most users
don't want them repaired and if you don't know how a microwave works,
then you have no business being inside of one.
