Abstract-
In this paper, a new complementary gate driver for power metal-oxide semiconductor field-effect transistors and in sulated gate bipolar transistors is presented based on the use of a piezoelectric transformer (PT). This type of transformer has a high integration capability. Its design is based on a multilayer struc ture working in the second thickness resonance mode. A new de sign method has been used based on an analytical Mason model in order to optimize the efficiency, the available power at the trans former secon ....etc

MOSFET BASED SINGLE PHASE INVERTER



1. INTRODUCTION
1.1 GOAL
“To explain theme of the project”

• INVERTER
A device that converts DC power to AC power at desired output voltage and frequency is called an INVERTER. Some industrial applications of inverters are for adjustable speed ac drives, induction heating, stand by air craft power supplies, UPS (Uninterruptible power supplies) for computers, HVDC trans ....etc

Logic Level MOSFET or Transistor Interfacing

Logic Level MOSFET or Transistor For Interfacing?
A logic level MOSFET may be easier. If you are using transistors to interface to the outside world you may find FETs simpler, easier and better!The traditional interfacing 'standard component' has always been the transistor. In fact I use these all the time on the bench but have you considered using a FET switch instead?There are now so called logic FETs switch are ideal for 5V operation because the threshold point is ....etc

DSTATCOM (Distribution STATic COMpensator) isused for compensation of reactive power and unbalance caused by II. SYSTEM CONFIGURATIONvarious loads in distribution system. This paper evaluates three Fig. 1 shows the basic circuit diagram of the DSTATCOMdifferent methods of determining the compensating current for a system with lagging power factor loads connected to 3-phase,DSTATCOM. The methods compared, are the instantaneous 3-wire distribution system. The lagging power-factor load isreactive power theory, synchronous referen ....etc
