The global trends towards energy efficiency have facilitated the need for
technological advancements in the design and control of power electronic converters
for energy processing. The proposed design is intended to make the practical
implementation of converters easier.
The development of a universal bidirectional galvanic isolated switch module will be
used to drive any MOSFET or IGBT in any position in any topology whether the
load is AC or DC. Semiconductor switches are required and are also integrated for
fast switching times in power converter applications
The structure of the power switch module consists of an opto-coupler which will
provide an isolation barrier for maximum galvanic isolation between the control
circuitry and power stage. It also consists of a high performance gate drive circuit
for high speed switching applications with a floating supply.
