The use of power diodes and Thyristors in applications such as small and large appliances, such as UPS systems, AC/DC rectifiers, and variable speed motor drives is the primary source of harmonic distortion in AC grid or mains current. Due to the source impedance of the mains power, the harmonic load current
Tantalum surface mount capacitors with a solid electrolyte have been the favorite capacitor technology choice in many electronic devices for more than five decades, thanks to their stability, high reliability, and superior volumetric efficiency. The traditional manganese dioxide (MnO2) cathode material provides
The technique of paralleling power converters and phase shifting their outputs is not new, and “interleaving” (as it is known) has been used in a number of applications to reduce the size of input and output capacitors. These include the 42V/14V DC-DC converters found in dual-voltage vehicle electrical systems
Advances in multilayer ceramic capacitor (MLCC) technology now offer designers a high-capacitance alternative to traditional electrolytic capacitors. New high-value MLCCs provide the advantages of lower equivalent series resistance (ESR) and inductance (ESL) than electrolytics, and demonstrated mean time to
Software is playing an increasingly prominent role in networking at a system architecture level, but it also has growing importance in the future in the delivery of power. Digital control, the use of power-optimization software algorithms and the concept of the Software Defined Power Architecture are all being
Alex Lidow, Efficient Power Conversion
Enhancement-mode gallium nitride transistors have been commercially available for over five years. Commercially available gallium nitride (GaN) FETs are designed to be both higher performance and lower cost than state-of-the-art silicon-based power MOSFETs. This achievement marks the first time in

Once upon a time electricity was magic in every sense of the word. From its humble yet fascinating triboelectric origins, where Thales of Miletus first noted amber can acquire an electric charge by rubbing with a material like wool. Many of America’s founders were also famous scientists and engineers (Benjamin
60 V EPC2035 and 100 V EPC2036 eGaN power transistors
Efficient Power Conversion Corporation (EPC) announced the 60 V EPC2035 and 100 V EPC2036 eGaN power transistors designed to compete in price, while outperforming silicon. Price, the last barrier to widespread adoption of GaN transistors as silicon MOSFET replacements, has fallen. These products demonstrate
