This article proposes a novel mean for tuning the natural frequency of an electromagnetic resonant shunt, using pulse-width modulation (PWM) circuit. It is used to modulate value capacitance and electrical shown be proportional command parameter PWM, duty cycle. An easy efficient strategy tune shunt in real time then proposed, thus obtaining low powered always stable vibration control device. T...

One of the parameters of the pulsed RADAR that contributes range capability is the average power of the transmitter. The average power can be increased by increasing the peak power or transmitted pulse width or both. The complexity in the design of transmitter components to withstand high peak power is the most challenging task. On the other hand larger transmitted pulse width affects the RADAR...

Multilevel inverters have become more popular over the years in electric high power application with the promise of less disturbances and the possibility to function at lower switching frequencies than ordinary two-level inverters. Multilevel inverters has been introduced as static high-power inverters for medium to high voltage applications such as large electric drives, reactive power compens...
