Belief Reliability Analysis of Electrical Performance Based on Analog Behavior Modeling

When calculating the belief reliability of electronic products, it is often used to establish a circuit simulation model to perform Monte Carlo analysis to obtain the key performance degradation parameters of the product. In this process, the lack of electronic component models is often a major difficulty that restricts this method. This article introduces the analog behavioral model (ABM) modeling method of electronic products, and gives the modeling process for power converters and relays, and substitutes the established model into a certain type of control circuit for transient simulation. Verity the usability of the model. Then use Monte Carlo simulation in circuit simulation to obtain key performance simulation results in the circuit. Finally, the belief reliability of the control circuit is calculated based on the principles of the four equations for the reliability.
