“…On the other hand, for relatively low power applications such as for PV systems with low power or auxiliary power in electric vehicles, a forward converter is usually recommended due to the simplicity of the design [4]. According to this, some studies on forward type resonant converters were carried out [4][5][6][7][8].…”

Forward converters have been broadly used in the power supply industry due to their simplicity, worthy efficiency, and low cost. A novel prototype soft-switched zero-voltage and zero-current ZVZC PWM DC-DC power converter with low voltage/current stresses is introduced for telecommunication power feeding in this paper. A new two-switch interleaved forward converter circuit is introduced to minimalize current circulation with no supplementary auxiliary snubber circuits. This converter circuit includes some outstanding benefits such as reduced components, improved efficiency, high power density and economic circuit configurations for high power conditioning applications. The simple operation principle is demonstrated on the basis of steady-state analysis. Furthermore, the effective feasibility of the proposed circuit topology is evaluated and verified practically for a 500 W–100 kHz prototype breadboard. The operation principle and steady-state characteristics are demonstrated from a theoretical point of view. To verify the practical effectiveness of the proposed power converter, a 500 W–100 kHz prototype converter using ultrafast IGBTs is implemented for a distributed telecommunication energy plant. The studied soft-switching converter is evaluated in comparison with the previously-proposed PWM converters in terms of voltage, current stresses, and operating efficiency.

Nowadays, various test equipment tend to be more intelligent, the test equipment of the volt-ampere characteristic of CT is so too. As the development of the electronics, VLSI(SCM) is manufactured. The purpose of our project is to scheme out a intelligent test system by the computer technique and the test technique. This equipment is mostly made of the SCM system and the peripheral equipment. We control the output of the digital transformer by SCM. The output voltage can make the TL494 create PWM wave. The wave is the control signal of the main circuit. The output wave of the main circuit is the sine wave, and the value of the output can be amended automatically. Compared with the traditional equipment, this equipment is smaller and use less energy, but its function is more powerful. It can be programmable. We can take it more expediently. So, this kind of equipment can be used widely in the future.

“…As the high frequency switching power supply makes power tube in the switch will generate a lot of wear and tear, and the emergence of the zero voltage and zero-current soft switch off technology just to solve the problem of excessive power dissipation in the power transistor switch process [1][2][3]. Want to perfect soft-switching technology to achieve switching tube requires further manufacturing process and electronic components in the circuit design.…”

Digital control algorithm common neural networks, fuzzy control, digital PID digital PID technology used widely and mature, the digital PID proportional, integral, derivative control the abbreviation. These advantages: simple in principle, applicability; little within the small range of the controlled object parameter changes on the performance indicators, a great guarantee the validity of the regulation. PID is the most successful control strategy in the analog control technology, digitized; people naturally will this control strategy is grafted onto the digital control technology. The system is digital PID.Used to implement a digital control chip has many, e.g., microcontroller, field programmable gate arrays (FPGAs), digital signal processor (DSP) and the microcontroller (ARM). SCM is the first large-scale application of the controller, but due to the speed of operation and the median can not meet the growing industrial control requirements. .
