Today's smartphones are not only tools for entertainment and communication, but also very effective tools for increasing the productivity of business users. End user can connect to company's IT infrastructure for uploading and downloading business data. However, smartphone security mechanisms have been discovered to offer very limited protection against malicious applications that pose a real threat...
EMI filtering is a critical driver for volume and weight for many applications, particularly in airborne and other mobile platforms. Because of the lack of ability to accurately predict system EMI behavior, EMI filter design usually cannot start until prototype EMI measurement results become available. This often leads to costly schedule delay and disruption, and the resulting design is suboptimal...
This paper presents a control design for single-phase power-factor-correction (PFC) converters using PWM-based multipliers. Multiplication between the input voltage and the output voltage compensator output is usually required for generating a reference for the input current in single-phase PFC control. Conventional PFC control ICs use linear multiplier circuits that have very limited operation range...
This paper presents a new current control method for dual-boost power-factor-corrected (PFC) converters which avoids the need for sensing the ac input current. The control method is a generalization to the nonlinear average current control previously developed for boost PFC converters that has demonstrated better control performance and reduced sensitivity to noise. The generalized method for dual-boost...
