intellivision 2 power supply

main switching circuit of the power supply is faulty. The pins 14 and 15 are short, the fan on the power supply does not rotate, and the purple Pin9 has a +5vsb voltage. This type of failure my typical maintenance example: 1). Open the Power box, found that two of the larg

by Intel in. The output power is generally ~ Between. The ATX Power Supply usually uses a 20Pin (20-pin) double-row rectangular socket to power the motherboard. With Intel's Pentium4 processor, the power specification is changed from ATX to ATX12V. Compared with ATX

discharge in time. However, this practice also brings a disadvantage, that is, the fan into more dust. Therefore, when the purchase of power to pay more attention to the design of the power supply fan, if the power supply fan in the dust design has a major breakthrough, co

the area are omitted. At present, the internal space of the power supply using a 12-centimeter fan is not able to plug in the integrated EMI filter, so most of the practices of both sides of the photo are used. ■ X capacitor (CX, also known as cross-wiring filter capacitor) This is a capacitor used in the EMI filter circuit to interwork between the wire (l) and the Neutral Line (N). It is used to eliminate

kHz (hard switch) and 300 kHz (soft switch ). The Technical Progress of IGBT is actually a compromise between the on-demand voltage drop, fast switch and high voltage capacity. Along with the technological and structural forms, IGBT has been developing in the history of 20 years. It has the following types: pass-through (PT) type, non-pass-through (treaty) type, and SPT type) type, groove type, and electric field cutoff (FS) type. Silicon carbide SiC is an ideal material for

fault. 2. When the lightning instantaneous into the machine, its powerful pulse current will be in the power supply impulse transformer generated instantaneous strong reverse induction pulse voltage, because this pulse voltage is far greater than the power regulator of the reverse breakdown voltage, resulting in the

formulas,That is, UO = Um × t1/TIn the formula, um is the maximum voltage value of the rectangular pulse, T is the Rectangular Pulse cycle, and T1 is the rectangular pulse width.As can be seen from the above formula, when um and t remain unchanged, the average DC voltage uo will be proportional to the pulse width T1. In this way, as long as we try to narrow the pulse width with the increase of the output voltage of the regulated power

Advantages and disadvantages of data center Power Supply System Solutions As a protection for the normal operation of the data center, the design and selection of UPS have core significance for the construction of the power supply system of the data center. In the current use of the data center, direct parallel and 2N

1. DSP6000 power-on sequence Problems DSP is indeed a freak. Two common problems are: (1) unable to connect to the CCS development environment; (2) burning chips. I am using TMS320C6713 now. The following experiences are based on DSP6000. Other series may be different. It seems that the performance of the chip has changed, and the chip has never been burned. However, CCS still often cannot be connected. Som

controller are higher and the cost is relatively high. In general, it is important to choose DCD for boostC, Buck, is the choice of DCDC or Ldo, to be compared in cost, efficiency, noise and performance. 　　Power supply is an indispensable component of all kinds of electronic equipment, its performance is directly related to the technical indicators of electronic equipment and the ability to work safely and

the power supply. Some sellers often mislead people to say that the high power is better than the low power. This is the most simple "pseudo knowledge ". Misunderstanding 2: confusion between rated power and maximum

countries for the compulsory certification of electronic products, such as the most familiar CCC certification is "Mandatory product certification System", which is the Chinese government to protect consumer personal safety and national security, strengthen product quality management, in accordance with the laws and regulations implemented a product conformity assessment system. Popular words is to have these certification can be in the market circulation and sale, if a

is at 220 volts. You can see an example in Figure 1. Upload Download Attachment(10.88 KB) Figure 1: Make sure the power supply is set to 220 volts. The next step is to check whether the fan is rotated. If the fan is rotating, the main power input must be working. If the fan is not rotated, either the fan is broken or the master

STM32 power management, stm32 Inverter Power Supply (1) 3-minute Model ① Sleep mode ② stop mode ③ standby mode 1. Sleep mode: Cortex-M3 kernel (can be understood as the CPU) stop working, CPU power 1.8V, peripherals in the operation, wake up from the original position after execution

tube, drain pole (d) is connected to the power supply pulse transformer, and the source pole (s) is resistor to the ground through 0.2 Ω, the adjusting tube gate (g) goes through the diode d910 (BYT42-M) to the ground. Remove the diode d910 from the circuit and test that the positive and reverse resistance is 5 Ω, which indicates that d910 has been broken down. The p
