Classification of Power
Converter Circuits
Detailed block diagram of a power electronic
system
• The function of the power
converter stage is to perform the
actual power conversion and
processing of the energy from the
input to the output by
incorporating a matrix of power
switching devices
• Power conversion refers to the
power electronic circuit that
changes one of the following:
– voltage form (ac or dc)
– voltage level (magnitude)
– voltage frequency (line or
otherwise)
– Voltage waveshape
(sinusoidal or nonsinusoidal,
such as square, triangle, or
sawtooth),
– Voltage phase (single-orthree-phase)
