Abstract
The 6-pulse controlled rectifier circuit is very well known. For proper operation of the 6-pulse rectifier, it is necessary to synchronise the firing signals with the mains voltage, else the operation of the rectifier is affected. A firing angle controller, without using any phase lock loop (PLL), is described here. This scheme employs the dq-reference frame to estimate the magnitude and phase angle of the fundamental component of the mains voltage. This method offers structural simplicity and immunity to mains voltage unbalance, harmonics and voltage sag etc.
