I. What is a High Voltage Power Supply?
A high voltage power supply typically refers to a device capable of outputting high voltages (ranging from several hundred volts to thousands of volts or even higher). It is primarily used to meet the specific requirements of voltage stability, precision, and safety in various applications. Depending on the voltage type and usage scenario, high voltage power supplies are categorized into DC high voltage power supplies, AC high voltage power supplies, and pulsed high voltage power supplies, among others. These different types play important roles across a variety of industries, particularly in high-energy physics research, medical equipment, precision testing, and industrial manufacturing.
II. Working Principle
The working principle of a high voltage power supply generally includes the following main steps:
· Input Rectification and Filtering: The input AC or low-voltage DC power is rectified and filtered to provide a smooth DC voltage, forming a stable input foundation for the subsequent voltage boosting process.
· Voltage Transformation and Boosting: Voltage is increased via a transformer or voltage multiplier circuits (such as a pulse forming network, PFN). Modern high voltage power supplies often utilize high-frequency switching technology, with digital control and feedback adjustment to precisely control the output voltage.
· Control and Feedback Regulation: Advanced control circuits and feedback mechanisms (such as PWM modulation, phase-shifting control, and soft-switching technology) are used to continuously monitor the output voltage and current in real-time. These systems automatically adjust to ensure stable and safe high voltage output.
· Protection Features: High voltage power supplies are typically equipped with multiple protection measures such as over-voltage, over-current, short-circuit, and temperature protection to ensure that the device can safely shut down or switch modes under abnormal conditions, preventing damage to components or harm to operators.
