Controller Design in Multisim Open-loop SMPSs rely on feeding a constant voltage to the input of a transformer or inductor, and assume that the output will be correct. Встроенный пилообразный генератор позволяет реализовать функцию регулировки мощности за счет изменения количества волн сетевого напряжения, поступающих к нагрузке за определенный интервал времени. With these components, you could accurately simulate your AC control or high-power rectification circuit performance.

Learn about the fundamentals of SPICE simulation. 4. Application Examples Higher efficiency, higher speed, and accurate control require powerful simulation capabilities and an optimized design environment to help designers become more productive in their prototyping approaches. Run the transient simulation of this circuit to evaluate the thermal performance of it on the desktop.

Passive Components (RLC) Parasitic behavior of passive components plays an important role in the performance of power circuits. Different controllers are available in the market, such as CPLDs, microprocessors, and DSPs, yet FPGA remains the most powerful technology.

These components allow you to accurately evaluate conduction and switching losses and SMPS circuits thermal behavior. In addition to the switches generic models, Multisim includes models for Silicon Controlled Rectifiers (SCR), and Gate Turn Off (GTO) switches. This type of SMPS designs is not practical and is no longer used in industrial applications. Also Multisim comes with over 500 new Infineon MOSFETS, with up to 3 levels of model complexity for intricate power applications such as thermal modeling. The IGBTs are the FS100R12KE3 parts from Infineon.

Based on the design requirements and the results of this comparison, the controller is able to make switching decisions and feed input back into the analog circuit to either switch a transistor on/off or activate/deactivate certain parts of it. Closed-loop SMPSs are the more practical designs where the controller is the feedback circuit that monitors the output voltage and compares it with a reference desired voltage. Multisim is equipped with a large number of standard models for these SMPS controllers. Running a transient simulation allows you to learn about the heating of the IGBT junctions, as well as how much power was lost during switching and conduction.

Multisim includes PWM, PWM complementary, and PWM three-phase generators. The capability of modeling these power components in Multisim takes advantage of the design and simulation fidelity of circuits like single-phase and 3-phase rectifiers; inverter circuits; and buck, flyback, and forward converters. All these modeling options give Multisim a big competitive edge over other tools. При этом, включение семистора осуществляется при переходе через ноль.
