Differences between electronic transformers and electronic ballasts
Electronic ballasts can be simply modified into electronic transformers, the output of high-frequency voltage can also be converted through the Xiaoji Diode rectifier DC. There is no voltage regulator circuit, the output voltage will change with the power of the load, so this circuit is called the electronic transformer instead of switching power supply.
Electronic transformer and electronic ballast in front of the self-oscillation circuit is basically the same, but behind the output of the circuit is different from the electronic ballast self-oscillation after the high-frequency voltage connected to an inductor, used to store light fluorescent, Transformer shock after the high-frequency voltage connected to a high-frequency transformer, used to 300V or so high-frequency voltage into 12V or so high-frequency AC, and then used to light 12v halogen bulb.
The ballast and it is not a thing at all, the ballast is the gas discharge lamp drive device, common is the fluorescent lamp ballast, there are inductive and electronic type, when the lamp starts to produce a momentary high voltage The gas is ionized in the lamp and then the lamp current is controlled to stabilize it. The electronic ballast is structurally similar to a half-bridge inverter circuit.
Electronic transformers usually refer to the switching power supply, in some cases it can replace the traditional power transformer to do power, so called electronic transformers.
