Q: What is the working principle of the power switch?: What is the working principle of switching power supply? ? Switching power supply is used to control the switch through the circuit for high-speed pass and cut off. ? The conversion of direct current into high-frequency alternating current is provided to the transformer for transformer, resulting in the required group or groups of voltages! Turn to high frequency pay The reason for the flow is the high frequency AC in the transformer transformer circuit efficiency than 50HZ Much higher. So the switch transformer can be done very small, and Work is not very hot!

Q: I do not understand the transformer should only work in the alternating voltage, but the switching power supply to the PWM IC output terminal connected to the primary input PWM IC has been rectified filter DC. Is the PWM modulation obtained by the high frequency of the exchange?: The transformer in the switching power supply is basically the same as that of a conventional power transformer, except that it has a feedback winding that provides a positive feedback signal to the PWM IC to cause high frequency oscillation along with the primary winding, Winding DC with a large AC component, the high-frequency AC components through the transformer core isolation in the secondary form of a pure high-frequency AC, rectifier filter after the supply of electrical equipment. Because the frequency is very high, compared to ordinary power frequency, switching power supply in the transformer and filter capacitor are greatly reduced.

Q: What is the difference between Switch Mode Power Supply and electronic switch? Where are they?: Switching power supply is a large class, usually we say that the switching power supply is AC variable DC power supply, but in fact, including DC variable DC, DC variable AC (inverter) should belong to the switching power supply.

Q: Switching power supply circuit will ring what will happen: Will not be regulated, the outcome is their own damage or damage to the load.

Q: We use the switching power supply is 220v-48v, the room has air conditioning, air conditioning power in 6kw or so, the total power of this room in 17kw, DC current is 60A, the room has two tubes. Now do not know how much switching power supply losses, these devices may have 17kw power? This is the 17kw power meter on the show. Who heroes help me.: Are you going to calculate the actual power consumption of the switching power supply? This requires knowing the load current or load power of the switching power supply and the efficiency of the switching power supply. General switching power supply efficiency (220v-48v) is greater than 80%, 80% efficiency, its power consumption is equal to the load / 80%.

Q: Switching power supply: A voltage is converted to another voltage, the crude pressure is converted to fine pressure

Q: Switching power supply 220 / 24V input break can be frequent power off: In fact, the general power is not particularly large switching power supply by the transformer independent of a group of windings for the chip power supply, so the power to start the power supply, so that the power is turned on and then plugged into the plug When only a large resistor can be used directly to start the chip, to be stable output, so there will be a little start-up time

Q: How to quickly analyze the switching power supply failure and timely repair: Maintenance of ATX switching power supply, starting from + 5VSB, PS-ON and PW-OK signals to locate the fault area, is an effective way to quickly check the line. 5VSB, PS-ON, PW-OK control signal ATX switching power supply, rely on + 5VSB, PS-ON control signal combination to achieve the power on and off. + 5VSB is the power supply for the host system in the ATX standby state, as well as open and close the automatic management and remote wake-up communication related to the working power of the relevant circuit, in the standby and controlled start state, the output voltage is 5V high, The purple line leads from the ATX plug 9 feet. PS-ON for the host to open or close the power or network computer remote wake-up power control signal, different models of ATX switching power supply, standby voltage value of 3V, 3.6V, 4.6V different. When you press the POWER switch of the main unit panel or enable the network to wake up the remote power on, the PS-ON is controlled by the electronic switch of the motherboard after the start, and the green line is input from the ATX plug. PW-OK is for the motherboard to detect the power output signal is good or bad, the use of gray line from the ATX plug 8 feet lead, standby state is zero level, controlled start voltage output stable after the 5V high.

Q: Switching power supply OLP and OCP these two are the same concept?: Not the same concept. OCP is overcurrent protection, many electronic devices have a rated current, not allowed to exceed the rated current, or will burn out the equipment. OLP is overload protection, to prevent the main power lines due to overload caused by overheating protection and installation of overload protection equipment.

Q: Isolation switch power supply and non-isolated switching power supply advantages and disadvantages,: Non-isolated type: Advantages: simple structure, small size, low cost; wide output voltage adjustment range Disadvantages: before and after the isolation, if the electricity supply, people touch the power output or the end of the ground may be risk of electric shock; only boost or buck or polarity conversion, the output voltage can not be equal to the input voltage. Scope: Input is within 36V low voltage (such as battery power supply); the entire circuit, including the ground can not be exposed to the occasion (such as dimming lamp)
