ViPEC Network Analyzer

ViPEC is a powerful tool for the analysis of high frequency, linear electrical networks. It takes a schematic description of the electrical network and performs a linear analysis in the frequency domain.

ViPEC Network Analyzer

The output is in the form of port parameters (S, Y or Z) with results presented on a user defined grid, Smithchart or table. It can also be used to compute other characteristics like stability factors and group delay.

ViPEC Network Analyzer

ViPEC supports various lumped elements (capacitors, resistors etc.) as well as distributed networks like transmission lines, microstrip and stripline structures. Two port data files are also supported (e.g. the 2-port frequency parameters of various RF transistors as supplied by the manufacturer). The component library is under constant development with new elements added at regular intervals.

Fairchild Semiconductor - Power Optimization

Manufacturer of Semiconductors that are used in Power supplies for products like cell phone chargers, set-top boxes to industrial controls. Fairchild Components are used in Mobile and Handheld Devices for power, backlighting and signal conditioning solutions for a longer battery life.

Fairchild is now part of ON Semiconductor

Fairchild Semiconductor - Power Optimization

The lighting is moving from power hungry incandescent bulbs to fluorescent, LED or HID lamps. Fairchild Semiconductors have designs for Lighting applications too.

Smart Power Module SPM evaluation board

This motion Smart Power Module SPM evaluation board is designed to evaluate Fairchild Semiconductor’s SPM3V2_V4 and SPM45H SPM families of parts.

The motion SPM is installed as the motor power module on the evaluation board to drive a three-phase AC Induction Motor (ACIM), Brushless DC (BLDC) motor, Brushless AC (BLAC) motor, or Permanent-Magnet Synchronous Motor (PMSM). A Switched-Mode Power Supply (SMPS) is integrated into the design, along with the necessary bulk capacitors and microcontroller (MCU) interface circuitry.

Logisim -Simulate Digital Logic Circuits

Logisim is an educational tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits.

Logisim -Simulate Digital Logic Circuits

Logisim -Simulate Digital Logic Circuits

With the capacity to build larger circuits from smaller subcircuits, and to draw bundles of wires with a single mouse drag, Logisim can be used (and is used) to design and simulate entire CPUs for educational purposes.

Some Features
  • The wiring tool draws horizontal and vertical wires, automatically connecting to components and to other wires. It's very easy to draw circuits!
  • Circuit layouts can be used as "subcircuits" of other circuits, allowing for hierarchical circuit design.
  • Included circuit components include inputs and outputs, gates, multiplexers, arithmetic circuits, flip-flops, and RAM memory.
  • The included "combinational analysis" module allows for conversion between circuits, truth tables, and Boolean expressions.

High Efficiency Step Down Isolated Supply

60W AC-DC adapter, synchronous rectification, fixed frequency current mode PWM controller. Very Low Quiescent Burden, Efficiency above 85%. That's Green.

STMicroelectronics - EVALSTSR30-60W. Synchronous rectification using L6668 and STSR30.

EVALSTSR30-60W: 60W AC-DC adapter
EVALSTSR30-60W: 60W AC-DC adapter

The converter works in both Continuous and Discontinuous conduction mode depending on the input voltage (the circuit has a wide input voltage range) and the output load. The 68-kHz switching frequency provides a good compromise between the transformer size and the harmonics of the switching frequency, optimizing input filter.

High Efficiency Step Down Isolated Supply

The input section includes protection elements (varistor, fuse and NTC for inrush current limiting), a standard Pi-filter for EMC suppression, a bridge and an electrolytic bulk capacitor as the front-end AC-DC converter. The transformer is a layer type, uses a standard ETD34 ferrite core and is designed to have a reflected voltage of 95V. The power MOS is a 700V - 1Ω and a transil clamp network is used for leakage inductance demagnetization.
