The following control methods are used for programmable DC power supplies in order to obtain stable voltage and current.
|Series regulator power supply||Stabilization is achieved by placing a control circuit between the input and output.||Very little noise.
Fast response speed.
Large and heavy.
|Switching power supply||Input is switched on and off to create high frequency, which is then rectified, controlled, and stabilized.||Good efficiency.
Small and lightweight.
Wide range of input voltage.
|Lots of noise compared to a series regulator system.||
Programmable DC power supplies can be largely divided into two categories: Constant-voltage DC power supplies that have a stable output voltage even when the load changes, and constant-current DC power supplies that have a stable output current.
Constant voltage is also referred to as CV, while constant current is referred to as CC.
