T Veg

T. Veg

Reginald s a T. Rex just as fierce and ferocious as the rest: he s got a mighty roar, gnashing teeth, and all the speed a dino could need. But when it comes to mealtime, Reg would rather chow down on broccoli, beans, and greens than the juicy steaks his paleo pals prefer. When Reginald realizes how different he is from the others, he hopes to find a place to fit in among the herbivores. He excitedly strikes out in search of a new herd, only to scare away the other dinosaurs as he charges to greet them. But when a falling boulder threatens the safety of Reg s old T. Rex clan, he ll show everyone what only a strong, vegetarian Tyrannosaurs rex can do. A celebration of vegetarianism, T. Veg is a rollicking laugh-out-loud tale about being unapologetically yourself.

Pulse Width Modulation In Power Electronics

This book provides a theoretical discussion of pulse width modulation (PWM) in power electronic inverters. Pulse width modulation is widely used for the frequency control of speed of ac motors, the design of uninterruptible power supplies (UPS) as well as the integration of renewable energy sources into existing power grid systems. PWM technique is based on approximation of sinusoidal waveforms by sequences (trains) of rectangular pulses whose widths are properly modulated. This width-modulation results in the suppression of low order harmonics at the expense of amplification of high order harmonics which are suppressed by energy-storage elements in load circuits. The discussion covers various PWM techniques with a focus on the optimal time-domain PWM techniques proposed by the authors.
