Abstract: Background: Pulse laser has been proved as an effective tool to simulate single event effects. It is important to evaluate the single event effects in microelectronics circuitry for space science and engineering. Purpose: By the theoretical analysis and experimental comparison, we aim to determine pulsed laser simulation of equivalent single event transient of Pulse Width Modulation (PWM) controller with heavy ion. Methods: By changing the laser energy, we obtained the experimental data under different conditions, and compared with the experimental data under the heavy ion. Results: The experimental results proved that Single Event Transient (SET) effect of 868.3-MeV Xe heavy ion which has 65.2 MeV?cm2?mg?1 Linear Energy Transfer (LET) value is similar with that of 1.064 μm, 1–2nJ pulsed laser. Conclusion: The experimental results provide data supports for using the laser pulse to simulate SET test on the same type of current mode PWM controller.
