Dynamically stabilized indirect current controlled SPWM boost type 3-phase rectifier
Near-sinusoidal-waveform currents of unity power factor can be obtained from the sinusoidal PWM (pulsewidth-modulated) rectifier using indirect current control. It is shown that the indirect current control must compensate dynamically for LdI/dt or else the stability region is very restricted. When correctly compensated, the dynamic indirect current controller can operate arrays of identical bridge rectifier modules in parallel and/or in series to augment the power ratings. By evenly staggering the phase shifts of the triangular carrier to each module in the arrays, switching harmonics can be eliminated. High-quality waveforms can be synthesized with slow switching devices such as GTOs (gate-turn-offs) and even force-commutated thyristors. Switching losses are also reduced.<>
