Ángel Sáenz Electronic Components has launched a custom-designed, single-phase phase-angle converter. Its purpose is to synchronize the connection of the mains voltage at any point on the half-wave. This allows for reducing the RMS value of the output voltage to regulate the power delivered to the load according to a setpoint. As shown in the figure, the W1C 400V / 0-400V – 1000A + VF consists of two SEMIKRON thyristors connected in anti-parallel, an ultra-fast fuse for protection at the converter input, an RC protection circuit, and a proprietary BASA 9901 control board.
Typical applications for this single-phase converter include, among others: industrial temperature heating of electric ovens, light intensity control in incandescent lamps, soft starting of induction motors, transformer control, speed control of direct current motors, and control of electroplating baths.
