What is this stuff?

[Alain G]

thank you Alain,

but it's pretty crazy to put a chopper on an electric oven ... A stupid thermostat does the trick very well.

The thermal inertia of an oven is at least 10 to 20 minutes, what is the point of chopping the voltage to 10 kHz?

I know that inertia may seem to do well but it is more the radiation of the element on the surfaces to be cooked which makes it grilling which harms according to the distance in the food and the element, in my important opinion on the small countertop oven / toaster.


The same phenomenon is found on an electric baseboard heater, with contact thermostat and chopper you can see a clear difference in comfort especially at floor level compared to the ceiling where there is much less difference seen than the cold floor air is continuously pumped.

See you!

These are wave train dimmers (switching is done at zero crossing). The chopping frequency does not exceed a few Hz (it's already much better than a mechanical thermostat ...)

As we cannot switch exactly to zero crossing with a triac beast, it generates a little noise (far less than a phase angle dimmer) ...

the diagram of this filter shows that it is used above all to prevent external parasites from entering the device ... for example to protect a programmer or a microcontroller thermostat

if the goal was to protect the exterior devices, it would have been necessary to put the capacitor on the exterior side and the inductors on the interior side

there are effective interference filters in both directions, but this is obviously not the case!

this filter only protects the device from disturbance from outside

Chatelot Hi!

The noises from the device will still be attenuated even with the capacitor (s) towards the device, the capacitor attenuates the high frequencies and the self as well whether it is on one side or the other.

It also protects against sudden voltage surges such as lightning by attenuating what is of a higher frequency than 50 Hz and by draining to the capacitor.

That of Macro probably died after an increase in tension due to an unstable network in its sector.

these are just gadgets of questionable reliability.

Put a pair of copper, a thermostat, a ground, and a 15A circuit breaker. That's all you need for a Joule effect oven
