The working principle of programmable DC power supply can be divided into the following steps:
1. Filter Input This step is mainly used to filter out interference from the power supply, in order to avoid the impact of these signals on the stability of the power supply and the filterable oscillator. It converts alternating current to direct current while filtering out unnecessary signals and interference programs.
2. Convert AC power filtered by a rectifier into DC power. Rectifiers typically use silicon rectifiers or metal oxide field-effect transistors (MOSFETs) to wait for component configuration.
3. Main filter: Through the filter, the modified DC power supply is processed to remove pulsating components and obtain a stable DC power supply. Filters are typically composed of stable voltage components, such as capacitors and inductors. This process is mainly achieved through a voltage regulator, which or other types of voltage regulators can achieve a constant set of three terminal pressures to ensure continuous flow of power and output controllers.
The control mode of programming DC power supply can be analog control or digital control. Analog control mainly controls the output voltage by adjusting the gain and phase shift of the voltage control loop, while digital control controls the output and voltage characteristics by programming the phase adjustment ratio. It has higher control accuracy and stability, as well as better maintenance and expansion capabilities. In addition to basic power conversion functions, programmable DC power supplies also have the following characteristics:
1. Safe programmable control DC power supplies generally adopt preventive measures such as overcurrent protection, overvoltage protection, and over temperature protection to ensure the safety of the power supply and the safe operation of electrical equipment.
2. Programmable: It can control and adjust the output voltage, current and other parameters of programmable DC power supply, and achieve real-time data monitoring and control through digital control through programming.
3. High efficiency: The programmable DC power supply adopts high-efficiency rectifiers, filters and other components, which can reduce power loss and heat generation, and improve power supply efficiency.
4. A good DC control program source can meet different input voltage and current requirements, as well as power requirements of different devices, with different compatibility and adaptability.
5. The high reliability and programmable control DC power supply adopts high-quality components and strict production processes, which can effectively improve the stability and reliability of the programmable control DC power supply, ensuring long-term stable, efficient, and safe operation.
