I. Introduction
With the development of power electronic converter technology, all kinds of inverters based on Pulse with Modulation (PWM) have been widely used. At present, most of rectifier devices usually adopt non-controlled or semi controlled rectification technology [1]–[4]. The PWM -converters ensures:
A sinusoidal current waveform;
Control the network power factor;
The functional reversibility of the installation without resort to
an auxiliary bridge in the contrary to the traditional converters [4].
