The DC stabilized power supply is a device that converts 220V power frequency AC power into a regulated DC voltage. It needs to be transformed, rectified, filtered, and stabilized.
The four links work as follows:
(1) Power transformer: It is a step-down transformer that converts the 220V AC voltage of the power grid into an AC voltage that meets the needs and sends it to the rectifier circuit. The transformer ratio is determined by the secondary voltage of the transformer.
(2) Rectification filter circuit: The rectifier circuit converts the AC voltage Ui into a pulsating DC voltage. The filter circuit filters out the large ripple component and outputs a DC voltage U1 with a small ripple. Commonly used rectification and filtering circuits include full-wave rectification filtering and bridge rectification filtering.
(3) Filter circuit: Most of the AC components in the output voltage of the rectifier circuit can be filtered out to obtain a relatively smooth DC voltage. Each filter capacitor C satisfies RL-C=(3~5)T/2, or T is the input AC signal period, and RL is the equivalent load resistance of the rectification filter circuit.
(4) Voltage regulator circuit: The function of the voltage regulator circuit is to stabilize the output DC voltage and not change with the AC grid voltage and load changes. Commonly used integrated regulators are fixed three-terminal regulators and adjustable three-terminal regulators. Commonly used adjustable positive voltage integrated regulators are available in the CW317 (LM317) series. Their output voltages are adjustable from 1.25V to 37V. The simplest circuit external components require only one fixed resistor and one potentiometer. The chip has transition, overheat and safety protection, and the maximum output current is 1.5A.
A separate slip ring is a device that allows two or more rotating electrical shafts to be connected without having to pass the electricity through the shafts' bearings. This is often used in situations where there is a need to power something externally while the shaft is still turning. For example, a machine might have a drive shaft that powers it while also having a separate output shaft that needs to turn at a different speed. By using a separate slip ring, these two shafts can be powered without any interference.
Slip Ring Shaf is a key component of a slip ring. It is the shaft on which the rotary electrical contacts are mounted. The shafts must be strong enough to support the weight of the contacts and must be able to turn freely. There are many factors to consider when selecting a shaft material, including strength, corrosion resistance, and operating temperature.
