The current control is becoming a challenging task
for switched mode power supplies, while current sensorless
control solutions can avoid the instantaneous current
measurements that has been applied for mostly used power
factor correction topologies. However, multilevel type of
converters haven’t been considered to use with current sensorless
control (CSC). Hereby, the CSC is applied to three level neutral
point clamped converter, where special volt-second balance is
applied to inductor in order to keep average inductor’s current
value to track the reference signal during both discontinuous and
continuous current modes. The explanation of post-fitting and
pre-fitting current trajectories is done that are necessary for
proper transition between voltage levels. Experimental results
have confirmed the theoretical model.
