Application of High-Frequency Switch DC and Pulse Power Supplies in Aerospace and Medical Electrochemical Polishing

1. Description

Electrochemical polishing is a process that removes microscopic protrusions from the metal surface by electrochemical dissolution, resulting in a smooth and uniform surface. In aerospace and medical fields, components require extremely high surface quality, corrosion resistance, and biocompatibility, making electrochemical polishing one of the essential processes.

2. Working Principles of High-Frequency Switch DC and Pulse Power Supplies

2.1 High-Frequency Switch DC Power Supply A high-frequency switch DC power supply converts the utility frequency AC to high-frequency AC, and then rectifies and filters it to provide stable DC power. The operating frequency typically ranges from tens of kilohertz to several hundred kilohertz, with the following features:

High Efficiency: Conversion efficiency can exceed 90%, resulting in low energy consumption.

High Precision: Stable output current and voltage with fluctuations less than plus-minus 1%.

Fast Response: Quick dynamic response, suitable for complex process requirements.

2.2 Pulse Power Supply A pulse power supply is based on high-frequency switch power supply technology and outputs periodic pulse currents via a control circuit. Features include:

Adjustable Pulse Waveform: Supports square waves and DC.

High Flexibility: Pulse frequency, duty cycle, and amplitude can be independently adjusted.

Improved Polishing Effect: The intermittent nature of pulse currents reduces electrolyte polarization and improves polishing uniformity.

3. Characteristics of Electrochemical Polishing Power Supplies for Aerospace and Medical Fields

Power supplies used in electrochemical polishing for aerospace and medical applications must meet high standards for product quality, safety, and reliability. Therefore, they need to have the following characteristics:

3.1 High Precision Control

Current and Voltage Stability: Electrochemical polishing for aerospace and medical components requires extremely high surface quality, so the power supply must provide highly stable current and voltage, with fluctuations usually controlled within plus-minus 1%.

Adjustable Parameters: The power supply should support precise adjustments for current density, voltage, and polishing time to meet the needs of different materials and processes.

Constant Current/Constant Voltage Mode: Supports constant current (CC) and constant voltage (CV) modes to accommodate different stages of the polishing process.

3.2 High Reliability

Long Service Life: The production environment in aerospace and medical fields demands high equipment reliability, so the power supply should be designed with high-quality components and advanced designs to ensure stable operation over long periods.

Fault Protection: Features such as overcurrent, overvoltage, overheating, and short-circuit protection to prevent damage to workpieces or production accidents due to power supply failures.

Anti-Interference Capability: The power supply should have strong electromagnetic interference (EMI) resistance to avoid disruption to sensitive medical or aerospace electronic devices.
