Q:What is the meaning of the regulator accuracy?
Regulator accuracy is the output voltage regulation accuracy single-phase 220V three-phase 380V conventional are 3% higher accuracy of the output voltage more stable, of course, the more expensive the price
Q:How to choose a regulated power supply
First you use the power supply to determine the load, such as you want to access the load voltage is 12V, the load current is 4.3A, then you choose to power supply, we must choose 12V / 5A power supply.
Q:How to control the DC regulated power supply output current constant?
Power supply can not do, you need is a constant current source.
Q:Adjustable DC regulated power supply works
(3) filter circuit: the rectifier circuit output voltage in the majority of the AC component to be filtered, resulting in a relatively smooth DC voltage of the filter capacitor C to meet RL-C = (3 ~ 5) T / 2, or T For the input AC signal period, RL is the equivalent load resistance of the rectifier filter circuit. (4) voltage regulator circuit: the function of the regulator circuit is to stabilize the output DC voltage, does not change with the AC grid voltage and load changes. Commonly used integrated voltage regulator has a fixed three-terminal regulator and adjustable three-terminal regulator. Commonly adjustable adjustable positive pressure regulator with CW317 (LM317) series, their output voltage from 1.25V-37V adjustable, the simplest circuit external components only a fixed resistor and a potentiometer. The chip has a transition, overheating and safe working area protection, the maximum output current of 1.5A. The output voltage Uo expression: Uo = 1.25 (1 + R2 / R1) where R1 generally take 120-240 ohms, the output and the adjustment of the end of the output voltage regulator, the output voltage Uo of the expression: Uo = 1.25 (1 + R2 / R1) The differential pressure is the reference voltage of the regulator (typically 1.25V). I uploaded the principle of switching power supply and write the above design.
Q:What is the main domestic DC power supply brand?
Intel Rock, Guwei, Edwards, the more popular use of domestic brands, Guwei, Edward brand history to be a long time, Intel is a relatively new star brand, three of the quality are
Q:Electrical Engineering! Why can not directly use a multimeter to measure the power supply of the exchange of ripple?
In general, multimeter AC can only measure the pure AC voltage. The output voltage of the regulated power supply is equivalent to the DC voltage + ripple voltage, and the multimeter exchange file can not be measured normally In addition, the ripple voltage is not necessarily a sine wave voltage, the regulated power supply itself or by external interference will produce complex ripple voltage, and the general multimeter AC voltage file is measured the average AC voltage. The ripple voltage is not a pure sine wave when the multimeter can not be accurately measured From the other side, the general linear power supply can only guarantee the output voltage in the lower frequency range of stability, and for more than tens of kHz ripple rejection is very limited. That is ripple voltage frequency is generally high, may have exceeded the multimeter AC file frequency response range, this time the multimeter is still unable to correctly measure
Q:In the use and installation of the regulator, what should be noted
Second, the security matters ⒈ power supply in the power supply start, do not arbitrarily open the regulator power supply or pull the power supply input and output connections to prevent electric shock or other electrical safety accidents. ⒉ power supply input and output power supply must be arranged reasonable to prevent trampling worn, resulting in leakage accident. ⒊ power supply must be reliable grounding, due to non-ground wire operation caused by electric shock or human injury, by the user responsible for their own. ⒋ power supply can not be connected to the power line in the heating pipes, water pipes, gas pipelines and other public facilities, so as not to infringe the rights of third parties or cause harm. ⒌ should regularly check the power supply input and output connection, so as to avoid loose or fall off, thus affecting the normal use of power supply and safe power. ⒍ voltage regulator cable matching must meet the provisions of the current capacity to carry enough capacity of the cable. ⒎. Regulator should be gently, in the work of time to avoid severe vibration; ⒏, to ensure that the regulator of the carbon brush spring has enough pressure to avoid the carbon brush and coil contact surface flash; ⒐, non-professionals please do not open the regulator power supply or power supply for maintenance.
Q:What is the difference between DC regulated power supply and AC regulated power supply?
DC is called DC AC is called AC Exchange to transformer Do not use an external transformer
Q:BEC (UBEC) and adjustable buck regulator power supply is different
BEC full name is battey elimin In the electric circuit set up a circuit module, the 12V battery output voltage turn Switch to 5V-6V to the receiver and steering gear and other electronic equipment (of course, the motor or 12V power supply) This eliminates the need for that 5 V battery This is the origin of the BEC (battery-free circuit) name. BEC mostly use linear regulator, linear regulator of the excellent way
Q:Why Capacitor Filtering in DC Regulated Power Supply
Large capacity capacitor or energy storage components! Can improve the power of the power load performance! The same can also short-circuit return residual high frequency And AC signal!
