If the rectifier voltage output and related electronic devices are normal, the operating point of the circuit should be further checked. I f a device with a damaged or variable value is found, n ormally the regulated power supply can be restored to normal after updating. is good, whether the capacitor has a breakdown, short circuit or open circuit. If the rectified voltage output is normal, but the output voltage is not normal, you need to further test whether the performance of the regulator tube, amplifier tube, etc. Therefore, during maintenance, it is necessary to first measure whether the rectified output voltage is normal. I f this rectified output voltage has a group of abnormal, then the regulated power supply will have a variety of faults. In all kinds of regulated power supply, there are one or more groups of the rectified output voltage. Measurement of Rectifier Output Voltage.Then open the casing cover to see if the power transformer has scorched taste or mildew and whe ther the resistance and capacitance have obvious damage phenomena, such as scorching, mold-breaking, liquid leakage, cracking and so on. You should first check if the fuses are fused or loose, whether the terminals are loose or short-circuited to the ground, and whether the gauge needle of the voltage indicator is jammed. I II Maintenance of DC Regulated Power Supply 3.1 Maintenance ProceduresĪll kinds of voltage-regulated power supplies are generally equipped with overload or short circuit protection fuses and input and output terminals. The main contents of the test are the regulation range of the output voltage, the stability degree, the ripple voltage and the overcurrent protection and so on. In order to make the electrical equipment work properly and not to affect the stable and reliable operation of the electrical equipment because of the poor performance of the DC power supply, it is best to test it simply before acting on the regulated power supply.

Before energizing, use a multimeter to measure whether the output voltage meets the requirements, so as to avoid damage to electrical equipment due to excessive voltage. If you need to output a negative voltage, you need to reverse the above wiring method. If it is necessary to output a positive voltage, the output terminal of the DC stabilized power supply "-" is connected to the "ground" terminal of the electrical equipment, and the terminal "+" should be connected to the required positive voltage terminal. Pay attention to the polarity of the required DC voltage when using it. The use of a DC stabilized power supply is very simple. II Application of DC Regulated Power Supply

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 RIPPLE EFFECT 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.
