A torque converter, which is a hydrodynamic clutch in automatic transmissions, transmits power from the engine shaft to the transmission shaft either by dynamically multiplying the engine torque or by rigidly coupling the engine and transmission shafts. The torque converter is a critical element in the automatic driveline, and it affects the vehicle’s fuel consumption and longitudinal dynamics....

Even though it has been shown that residue number systems (RNS) provide very fast and reliable arithmetic due to its inherent parallel processing and error correcting capabilities, its use is severely limited to a few applications due to the complexities involved in its conversion circuitry. Moreover, the detection of errors and their correction form an important aspect of any digital design. I...

This paper presents an interleaved active-clamping zero-voltage-switching (ZVS) forward-flyback converter without an output choke. The presented topology has two active-clamping circuits with two separated transformers. Because of the interleaved operation of the converter, the output current ripple will be reduced. The proposed converter can approximately share the total load current between t...

In this paper, CM noise suppresion and magnetic elements winding loss optimization design of a cascade power module based on GaN are carried out (the front stage is buck converter, the second LLC resonant converter). To suppress noise, converter adopts planar stagger reverse coupling inductance, by establishing model conduction path model, equivalent capacitance can effectively reduced, thus fu...

The reverse conduction mode of operation of the SiC trench JFET allows for diode-free synchronous rectification. This paper shows that the reverse conduction mode is an inherent property of the device caused by diffusion of electrons through the source fingers under conditions of moderate gate-drain diode forward bias. Experimental results confirm the expectations for a vertical-channel SiC JFE...

In this paper, a new ZVT forward converter is presented in which the third winding of utilised to transfer power from input output, recover energy leakage inductance and snubber capacitance, also provide ZVS condition for switch. proposed converter, main switch turned ON OFF under condition, auxiliary operates ZCS condition. Besides, all diodes are their reverse recovery losses alleviated. More...

Most of modern controlled electric drive applications, such as lifts, cranes, and tooling machines, are characterized by a high ratio of the peak to average power. In addition, such applications have high demand for braking at the full rated power. In ordinary drives, the braking energy, which represents 30%–50% of the consumed energy, is dissipated on a brake resistor. Apart from this ―energet...
