Working Principle of Electronic UV Power Supply for UV Curing Lamps:

The working principle of the electronic ballast/electronic uv power supply for medium-pressure ultraviolet lamps is as follows:

 I. Input power supply

Connect to an alternating current uv lamp power supply, generally mains power.

 II. Rectification and filtering

1. Firstly, the alternating current power supply is converted into pulsating direct current power through a rectifier circuit (usually composed of diodes, etc.).

2. Then, through the filtering stage, components such as capacitors and inductors are used to filter out the ripples in the direct current to obtain a relatively smooth direct current voltage.

 III. High-frequency inversion

1. Electronic switching elements (such as transistors, field-effect transistors, etc.) are used to convert the smooth direct current voltage into high-frequency alternating current voltage.

2. By controlling the conduction and turn-off time of electronic switching elements, the frequency and amplitude of the output high-frequency alternating current voltage can be adjusted.

 IV. Starting the medium-pressure ultraviolet lamp 

1. The high-frequency alternating current voltage is applied to the medium-pressure ultraviolet lamp to generate a high-voltage pulse to start the discharge process of the lamp.

2. Once the lamp is started, the electronic ballast will adjust the output to maintain the lamp in a stable working state.

 V. Control and protection 

1. The uv lamp power supply usually also contains a control circuit for monitoring the working state of the lamp, such as current, voltage, power, etc.

2. When abnormal conditions occur, such as overcurrent, overvoltage, overheating, etc., the protection circuit will act and cut off the power supply to protect the uv lamp and the Electronic UV Ballast itself.

     In Brief, the electronic uv ballast/uv power supply processes the input alternating current through electronic components (such as inductors, capacitors, transistors, etc.) by rectification, filtering, and inversion, and converts it into high-frequency alternating current suitable for the operation of uv curing lamps. After the circuit is connected, the electronic uv ballast first provides a relatively high starting voltage to excite the gas discharge in the uv curing light tube and make the lamp tube start to emit light. After the lamp tube is started, the ballast then limits the current to a stable range to ensure the normal and stable operation of the uv curing lights in the uv curing equipment.
