Title: Improvements in or relating to a self-regulating electronic inverter
IPC: H02M7/51
Filed: 1959-01-29
Abstract: 886,355. Automatic voltage control systems; inverters. SOC. FRANCAISE DE TELECOMMUNICATIONS NOR. Jan. 29, 1959 [Jan. 31, 1958], No. 3203/59. Classes 38 (2) and 38 (4). In an inverter including two thyratrons the output voltage is regulated by inserting in the anode circuits two reactors whose inductances depend on the output voltage. The anodes A2, A3 of the thyratrons H2, H3 are connected together through commutating condenser C, and also through condenser C1 in series with the primary P2, P3 of a transformer from whose secondary the output voltage is obtained. The anodes are connected to the D.C. source E through reactors L2, L3 forming the primary windings of transformers T1, T2. The secondary S of the output transformer is connected to a rectifier bridge RD which supplies exciter windings Q1, Q2 arranged in parallel, with D.C. proportional to the alternating output voltage. Exciter windings Q1, Q2 are wound on saturable cores and determine the inductances of windings I1, I2 which are connected respectively to secondaries S2, S3 of transformers T1, T2, and which therefore determine the inductances of primaries L2, L3. In a modification regulation of the peak voltage is obtained by supplying windings Q1, Q2 with a voltage proportional to the difference between the inverter voltage, rectified and filtered, and a direct reference voltage. In a second modification the effective voltage of the inverter is regulated by comparing a direct reference voltage with the voltage drop across a resistance in the anode circuit of a diode whose filament is heated by the output voltage of the inverter.
