The use of a DC stabilized power supply is very simple. II Application of DC Regulated Power Supply
PRINCIPLE APP COMPONENT SERIES
It consists of a rectifier filter circuit, series voltage regulated circuit, auxiliary power supply and protection circuit. The typical circuit block diagram of transistor series DC regulated power supply is shown in figure 1. II Application of DC Regulated Power Supplyģ.2 Common Examples of Troubleshooting of Voltage Regulated Power Supply
Therefore, transistor DC regulated power supply is a necessary instrument commonly used in scientific research, production, teaching, maintenance and other departments.
PRINCIPLE APP COMPONENT VERIFICATION
The precision stabilized current power supply can also be used as the stabilized current power supply for the verification of some electrical instruments. Transistor DC regulated power supply can be used as DC power supply for various transistor meters, electronic computers, automatic control systems and equipment. Therefore, a DC power supply with stable voltage is usually required. For precision measuring instruments, automatic controls or electronic calculation devices, it will cause measurement and calculation errors, and even affect normal operation. Voltage fluctuations of the DC power supply will cause unstable circuit operation. If the load current is small, the output voltage is high if the load current is large, the output voltage is low. When it flows through the internal resistance of the rectifier, it will produce a fluctuating voltage drop on the internal resistance, causing the output voltage to fluctuate with the fluctuation of the load current. Although it can be used as a DC power supply, due to the fluctuation of the grid voltage, the rectified DC voltage output will also fluctuate.Īt the same time, the load current in use is also constantly changing, some of which vary greatly. After rectification and filtering, AC becomes DC. When supplying power from the AC grid, it is necessary to convert the AC grid power supply into a stable DC power supply. In the verification and maintenance of the indicator instrument, in addition to the appropriate standard instrument, there must also be a suitable DC power supply and regulating device.
