Abstract All‐solid‐state switches are one of the core components pulsed power supply systems. However, voltage level a single switch is limited. By optimizing chip structure, can be improved. Due to immaturity production process and positive correlation between blocking on‐resistance switch, it difficult improve continuous forward current simultaneously. The series‐connected way increase switch...

According to the International Technology Roadmap for Semiconductors in the next 10-15 years the limits imposed by the physics of switch operation will be the major roadblock for future scaling of the CMOS technology. Among these limits the most fundamental is represented by the so-called Shannon-von Neumann-Landauer limit that sets a lower bound to the minimum heat dissipated per bit erasing o...

–Harmonic pollution and low power factor in power systems caused by power converters have been of great concern. To overcome these problems several converter topologies using advanced semiconductor devices and control schemes have been proposed. This investigation is to identify a low cost, small size, efficient and reliable ac to dc converter to meet the input performance index of UPS. The per...

Classification, essential properties, important applications and developement of power semiconductor devices will be explained. Some common power semiconductor devices, power metal oxide semiconductor field-effect transistor (MOSFET), thyristor and some new power devices will be described and discussed.

The medium voltage DC (MVDC) type system can connect multiple terminals to a common MVDC bus, so it is possible several renewable power sources the but circuit breaker needed isolate short accidents that may occur in bus. For this purpose, concept of hybrid takes advantage low conduction loss contact switch and an arcless-breaking semiconductor has been proposed. During break switch, dedicated ...

Power Semiconductor switches of active rectifier are characterized by highly nonlinear property, resulting in high harmonic distortion and high ripple voltage on the DC side. This paper presents advanced control using switch function and fuzzy logic for compensating nonlinear behaviour. The system applies switch function of time as the input of control strategy, instead of current and voltage i...

The CLW modulator represents the first successful application of high-power IGBT switching modules to meeting the requirements of multi-megawatt peak power modulators for microwave amplifier applications. Unlike some other solid-state modulators, no semiconductor switches are placed in series in this system. Neither are the switches connected in parallel. Rather, each switch drives a segment of...

Nanoelectromechanical (NEM) switches are similar to conventional semiconductor switches in that they can be used as relays, transistors, logic devices and sensors. However, the operating principles of NEM switches and semiconductor switches are fundamentally different. These differences give NEM switches an advantage over semiconductor switches in some applications--for example, NEM switches pe...

RF and microwave communication systems rely on frequency, amplitude, and phase control circuits to efficiently use the available spectrum. Phase control circuits are required for electronically scanning phase array antennas that enable radiation pattern shaping, scanning, and hopping. Two types of phase shifters, which are the phase control circuits, are most ot'ten used. The first is comprised...
