January 2020 – v4.2
New DC-DC converter: Phase shifted full bridge
- Phase shifted full bridge (PSFB) DC-DC converters are used frequently to step down high DC bus voltages and/or provide isolation in medium to high power applications like server power supplies, telecom rectifiers, battery charging systems, and renewable energy systems. This topology allows all the switching devices to switch with zero voltage switching (ZVS) resulting in lower switching losses and an efficient converter.
- SmartCtrl 4.2 allows the user to define the switches output capacitance (Coss) in order to study the conditions of the zero voltage switching (ZVS).
- Optimum control loop due to the high accuracy of the converter model included in SmartCtrl 4.2.
- The converter model considered in SmartCtrl 4.2 includes the effective duty cycle losses due to the transformer inductance leakage. The new steady state waveforms allows the user to review the operating point of the converter.
- Direct converter simulation in PSIM seamlessly integrated with SmartCtrl.
- Select with just one click between digital or analog control.
New PI compensator
- SmartCtrl originally includes a PI analog compensator to allow the user to get the values for its physical implementation. Now we have included the classical PI compensator using its transfer function combined with the PWM modulator. The transient response plot functionality has been revised and updated.
Custom defined sensor for predefined topologies
- Are you using Matlab or Mathcad? Do you already have the transfer function of your sensor? SmartCtrl is the perfect complement, thanks to the new functionality you can combine any of the predefined topologies with your own customized sensor.
- Now you can define, e.g., the transfer function of your specific implementation of the typical TL431 driving an optocoupler voltage sensing or any specific Hall sensor.
- Using the Parametric Sweep select the best control solution just using the sliders to change your sensor parameters.
