List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
PSIM is an Electronic circuit simulation software package, designed specifically for use in power electronics and motor drive simulations but can be used to simulate any electronic circuit. Developed by Powersim, PSIM uses nodal analysis and the trapezoidal rule integration [ 2 ] as the basis of its simulation algorithm.
The PWM's leading edge is held at the leading edge of the window and the trailing edge is modulated. Trailing edge modulation (middle plot) uses a normal sawtooth wave to generate the PWM. The PWM's trailing edge is fixed and the leading edge is modulated. Centered pulses (bottom) uses a triangle waveform to generate the PWM.
It is designed to run on 32-bit or 64-bit editions of Windows 7, 8, 8.1, 10, and macOS 10.9+. [2] Summary of major changes from LTspice IV to LTspice XVII are: Add 64-bit executables. [6] Add Unicode characters in schematics, netlists, plot. [6] Add device equations for IGBT, diode soft recovery, arbitrary state machine. [6]
TINA software is available in installable and cloud-based versions. Feature versions exist for use in industry [6] and for educational use. [2] [7] TINA allows simulation, design, and real-time testing of hardware description language (HDL), such as VHDL, VHDL-AMS, Verilog, Verilog-A, Verilog-AMS, SystemVerilog and SystemC and for microcontroller (MCU) circuits, [2] as well as mixed electronic ...
Quite Universal Circuit Simulator (Qucs) is a free-software electronics circuit simulator software application released under GPL. It offers the ability to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit.
Random pulse-width modulation (RPWM) is a modulation technique introduced for mitigating electromagnetic interference (EMI) of power converters by spreading the energy of the noise signal over a wider bandwidth, so that there are no significant peaks of the noise.
Fig. 2: Top and bottom views of an air-cooled 10kW-Vienna Rectifier (400kHz PWM). The Vienna Rectifier is useful wherever six-switch converters are used for achieving sinusoidal mains current and controlled output voltage, when no energy feedback from the load into the mains is available.
