For this week’s QSPICE schematic capture, Professor Marcos Alonso demonstrates a Phase-Shifted Full-Bridge (PSFB) converter model in QSPICE, showing transient startup behavior and key waveform responses including voltage stress, primary current, and output voltage settling. You can find this here: marcosalonsoelectronics (Marcos Alonso) · GitHub. You can find his most recent power electronics book here.
This type of simulation is invaluable for power designers because PSFB topologies are widely used in high-efficiency isolated DC-DC conversion for servers, telecom, EV charging, and industrial systems. With QSPICE, engineers can quickly analyze:
- startup overshoot
- resonant behavior
- switching stress
- control loop stability
The result: faster optimization and fewer surprises in hardware.
