Abstract: A single or multiphase converter connection includes a controlled first converter having an AC side and a DC side. A first reactor connects the DC side to a DC source. A capacitor is connected to the AC side of the first converter. A controlled current circuit is formed of a second reactor and controlled rectifiers connected to the second reactor to control the current therethrough. A control means is provided for firing said rectifiers with an adjustable delay angle so that the current circuit generates a variable capacitive current.

Abstract: A DC converter for controlling the average value of an intermittent direct current comprises a main thyristor which is ignited with a certain frequency and provided with an extinguishing circuit having an auxiliary thyristor, the ignition of which causes the extinction of the main thyristor. The extinguishing circuit further comprises an oscillating circuit which includes a reactor and a capacitor, which reactor is in series with the main thyristor as well as the auxiliary thyristor.

Abstract: A synchronizing device for achieving frequency and phase similarity between an output voltage from an inverter and the voltage from a second alternating voltage source includes an oscillator for delivering an output signal in the form of control pulses to the inverter, so that the input voltage of the inverter has a frequency corresponding to that of the control pulses. The second alternating voltage source supplies pulses to the oscillator to lock the output signal of the oscillator in frequency to the frequency of said alternating voltage source. The output signal of the oscillator is supplied to the inverter over a phase-shifting member. A phase-sensitive member is supplied with the output signal of the oscillator and the output of the inverter, and forms an analogue signal depending on the phase difference therebetween. This analogue signal is supplied to the phase-shifting member to affect the phase shifting so that the phase difference is steered towards zero.
