The working principle of a linear DC bench power supply begins with reducing the voltage amplitude of the AC power source using a transformer. The transformed voltage is then converted into pulse DC power through a rectifier circuit. After undergoing a filtering process, the output is a DC voltage with minimal ripple. In addition, a voltage regulation circuit is used to ensure high-precision output DC voltage.
Linear DC bench top power supplies are widely used in fields such as scientific research, laboratories, electrolysis, electroplating, and charging equipment. Their advantages include:
- High Output Stability: Linear power supplies exhibit minimal fluctuations in output voltage, making them ideal for devices that require extremely stable voltage.
- Low Ripple: Due to the incorporation of filtering circuits, linear power supplies produce very low ripple (the AC component in the output), ensuring clean and stable performance.
- Minimal Electromagnetic Interference (EMI): Linear power supplies generate very little electromagnetic interference during operation, making them particularly suitable for applications with stringent electromagnetic compatibility requirements.
- Simple Design: The relatively straightforward design of a DC linear power supply facilitates easier maintenance and troubleshooting.
