Absolutely, but this is a classic diagram of what is sold under the name "electronic transformer" for lighting.Alain G wrote:Your diagram includes an output transformer and is not the use of all chopped power supplies,
I did not say the contrary...Alain G wrote:in addition, we clearly see on the 2nd graph the 30 volt peaks which are harmful on an LED, this is why I recommend stabilizing this peak with a non-polarized condo on the use of LEDs!
For LEDS, you are absolutely right.Alain G wrote:A small classic 10 watt transformer costs as low as 5 euros so why buy these things!
Originally these transformers are designed for halogen bulbs and their main advantage is to be able to provide high power in a small volume and with low heat generation and a limited price.
In fact, the whole problem comes from the fact that we are trying to replace a halogen bulb with an LED bulb without other modifications to the luminaire, whereas it is the couple {transformer, bulb} that should be replaced.
