Question:

Can the rectifier change the voltage?

Can the rectifier change the voltage?

Answer:

Day off the light of the lighting voltage of more than 400 V, 220V how to start it, in fact, rely on the starter this thing, by the starter to produce a self-inductance electromotive force to light the lamp.
The correct call is "fluorescent lamp ballast", not the rectifier. The role of the ballast is: 1, fluorescent lamp start, the starter contact in the moment off, the ballast inductor electromotive force and power supply voltage superposition, the lamp mercury gas breakdown, to stimulate the fluorescent light. 2, the fluorescent light is lit, the ballast to play the role of impedance, limiting the current through the light.
With the starter of the fluorescent rectifier in the circuit is an inductor.Using the starter on and off the lamp at both ends of the high pressure to the lamp inside the gas conduction and light, the specific I have not measured, but 55V seems not too Correct
220V to form a loop and a current, lamp filament is heated to light to prepare (see the lamp red hair). After the two contacts of the starter, the neon ionization stops, the temperature drops, and the low temperature activates the contact, so that the two contacts are disconnected. At the moment of disconnection, the ballast produces a self-inductance voltage because of the "self-inductance". The self-inductance voltage 220V adds up to several hundred volts, and the mercury in the lamp is ionized at hundreds of volts Conduction, ionization of mercury emitted by radiation, according to the tube is the fluorescent material, the fluorescent material to send light.
Close the switch, the 220 voltage by the ballast, the lamp at both ends of the filament added to the starter, this time the lamp is not bright, the lamp is only played a role in the power supply to the starter. 220V added to the starter, the neon inside the ionization occurred (this time the red light), ionization of the neon temperature, high temperature so that the starter's movable contact to the static contact deformation, so that the two contacts Phase connected.
