چکیده
This paper presents an adaptive dead-time control circuit for a maximum work frequency 20 MHz, voltage level 90 V GaN gate driver. The is set to prevent straight-through of the upper and lower power transistors bridge arm structure ensure reliability motor For drivers on market today, fixed or configurable widely used in more-than-10 MHz application scenarios. However, switching loss caused by insufficient reverse turn-on excessive devices have hazardous influence efficiency drivers, which cannot avoid. driver with proposed has been implemented 0.18 um BCD process. dissipates 56.3 uA quiescent current simulation situation able provide 5 ns error

Investigation of purge time in cathodic dead-end mode PEMFC
Recently, special type of fuel cells has been developed that operates in a Dead End mode. Working in this condition, the Dead-End fuel cell is supplied withhydrogen almost at the same rate of consumption. It is noteworthy to mention thatall of the water transport mechanisms have been considered in this simulation.Water accumulation that is directly proportional to the cell current is of a grea...
متن کاملOn ℋ∞ control for dead-time systems
A mixed sensitivity problem is solved for dead-time systems. It is shown that for a given bound on the -norm causal stabilizing controllers exist that achieve this bound if and only if a related finite-dimensional Riccati equation has a solution with a certain nonsingularity property. In the case of zero time delay, the Riccati equation is a standard Riccati equation and the nonsingularity cond...

A mixed sensitivity H∞ problem is solved for dead-time systems. It is shown that for a given bound on the H∞-norm there exist causal stabilizing controllers that achieve this bound if and only if a related finite-dimensional Riccati equation has a solution with a certain nonsingularity property. In the case of zero time-delay the Riccati equation is a standard Riccati equation and the nonsingul...
متن کاملAdaptive Controller Design for the Control Systems with Dead-zone
An adaptive tracking control problem is investigated for a class of nonlinear system with non-symmetric actuator dead-zone fault. Based on adaptive compensation algorithm, a new adaptive controller specially designed is employed without constructing the dead-zone inverse. This paper studies the dead-zone fault model is more universal. The restrictions that the dead-zone slopes and the boundarie...
متن کاملDead-band self-triggered PI control for processes with dead-time
Current implementations of digital controllers assume that sensing, control and actuation are performed in a periodic fashion. In classic control schemes, where sensors and controllers are directly connected, periodicity does not provide particular drawbacks, but, in the case of wireless sensor networks, such a choice may be questionable. One of the driving constraints in the design of wireless...
