Automated power supply testing
… an Automated Testing system used to test a switched mode power supply. It includes all the basic principles found in industrially available Automatic Test Equipment (ATE). The system consists of a Testing Jig on which the testing is done, interfaced to a computer through a controlling card. …

An energy buffer for constant power loads
Constant power loads (CPLs) are a class of loads steadily increasing in use. They are present whenever a load is regulated to maintain constant output power, such as with LED drivers in high quality lighting that is impervious to input fluctuations. Because CPLs exhibit a negative incremental input …

Frequency and phase locking of a CW magnetron : with a digital phase locked loop using pushing characteristics
… of the magnetron with differing heater powers and load conditions when operated with a low cost switched mode power supply. We similarly identify three different regimes of the magnetron operation with respect to the heater power: firstly low noise operation for small heater powers (up …

Modeling and numerical methods for power electronic devices
A scalable I-V model for latch-up in non-collinear PNPN devices is adapted from a previous model for collinear SCR devices. The model is applied to 14-nm FinFET test structures. Layout scaling trends for key latch-up metrics, such as holding and trigger voltage, are captured by the model in circuit …

Digital-Based Zero-Current Switching (ZCS) Control Schemes for Three-Level Boost Power-Factor Correction (PFC) Converter
… laptop, monitor, LED lighting and server) in modern technology-driven lives, performance of switched-mode power supply (SMPS) for electronics have been growing to prominence. As front-end converters in typical SMPS structure, ac-dc power-factor correction (PFC) circuits play a key role in …
