Zero Voltage Switching Resonant Power Conversion
Zero Voltage Switching Resonant Power Conversion

... During the ZVS switch off-time, the L-C tank circuit resonates. This traverses the voltage across the switch from zero to its peak, and back down again to zero. At this point the switch can be reactivated, and lossless zero voltage switching facilitated. Since the output capacitance of the MOSFET sw ...

... Due to the economical point of view, it is mostly preferred to supply the IGBT gate driver for low power converters with an unipolar voltage 15V/0V instead of utilizing a bipolar supply voltage e.g. +15V/-15V. In this solution, the effect of a parasitic turn on can not be avoided without an addition ...

Stepper motor



A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
