"OrCAD" is the main schematic diagram of the circuit and for the production of PCB and programmable logic design to provide continuous simulation information.3. "PSPICE" main analysis circuit. First, based on the analysis of the basic circuit characteristics such as DC, AC and transient, the simulation circuit has realized the complex an

not porting to Windows at all, because Windows machines generally do not have enough capacity to run such a program. Do not think that PSpice is available only for Windows. It is much better for UNIX to use it, and it can run on large hosts. Of course they are not free, but they are worth that price.
However, some things in Windows are not very similar in Linux, or you find many similar things, but each of them is much worse than that in Windows, the

switch-stabilized power supply schematic diagram and equivalent principle block diagram, it is composed of full-wave rectifier, switch Tube VI, excitation signal, continuous current diode VD, energy storage inductor and filter capacitance C. In fact, the core part of the switching voltage supply is a DC transformer. Here we explain the DC converters and inverters as follows. Inverter, which is a device that converts DC to AC. Inverters are commonly u

Any framework that encapsulates JDBC cannot do without encapsulating the final data into a Java object. In JDBC, the obtained data is encapsulated in the resultset, and the corresponding fields and data values are obtained again and again through iterative resultset. The problem that the database framework always needs to solve is to map the field name in
Figure 1-24 refers to the voltage waveform of the energy storage filter capacitor charging according to the sine curve when all the charging time of the energy storage filter capacitor is combined. We can regard Figure 1-24 as an energy storage filter capacitor and charge the voltage to the maximum value after six working cycles, where T1, T2 ,... T6 represents toff1, toff2 ,... Toff6. Toff1 indicates the first shutdown time of the active switch, and so on. After the energy storage filter capaci

2. Main components
Good power, no lack of good detail
Large electrolytic capacitors, Schottky diodes, transistors and so on, the selection of these components directly affect the life of the power supply. Some manufacturers to reduce costs, the use of old materials, but manufacturers can not know the old devices still have how much life, it is likely that the factory soon, the device's life, light power outages, heavy device explosion.
