摘要： A control system that can accommodate the wide variations in the output of a generator, such as a permanent magnet alternator, while providing an output with relatively uniform phase ripple. The control system includes a zero crossing detector (206B) and variable ramp generator (208A) for generating control signals to a switching rectifier to generate a regulated DC signal .

摘要： A phase shift triggering circuit for thyristor, comprising synchronous signal sampling circuit, a waveform shaping, integrating and comparing circuit, a high-frequency modulating and pulse distribution circuit and a power amplifying high-frequency pulse rectifying output circuit, characterized in that said synchronous signal sampling circuit comprises a transformer whose secondary inductance and a capacitance form a LC resonant loop for selecting (via transformer coupling) synchronous signal from main circuit. A single thyristor integrated module is formed when the triggering circuit is connected with the main circuit, the module is compact and resistant to interference, can operate under wide range of voltage, without the demand on phase sequence and phase numbers.

摘要： For controlling the current in an inductive load, the gate current used to fire thyristors in a rectifier is controlled to reach zero at exactly the same time, within a given half-wave, as the current in the inductive load which receives the voltage from the rectifier, keeping gate voltage on as long as thyristor current is on. A discontinuous thyristor converter current signal is detected and used to generate an enable signal in conjunction with a thyristor gate voltage. The enable signal, in synchronism with a power supply line voltage, provides a pair of channeling signals which then, depending upon whether the field current is positive or negative, activate the gate voltages of the thyristors such that the gate voltages end exactly at that time, within a given half-wave, where the generator field current becomes discontinuous.

摘要： A power converter utilizes first and second thyristor bridges (14, 15) energized by two AC power sources (2, 3) which are insulated from each other. The power converter includes first and second auxiliary thyristor circuits (16, 17) each containing plural thyristors, and a commutation circuit (18). The cathode of each thyristor of first auxiliary thyristor circuit (16) is connected to one (2) of the AC power sources, and the anode of respective thyristors are connected each other at a common node (N1). The anode of each thyristor of second auxiliary thyristor circuit (17) is connected to the other (3) of the AC power sources, and the cathode of respective thyristors are connected each other at another common node (N2). The commutation circuit (18) is connected between the common nodes (N1, N2) of the first and second auxiliary thyristor circuits (16, 17).
