Title: Ignition circuit for a power thyristor
Inventor: THIELE GERD DIPL ING
IPC: H02M1/092
Filed: 1982-08-02
Granted: 1985-03-28
Abstract: A firing circuit for two antiparallel-connected power thyristors. Each of the power thyristors has a gate terminal; the gate terminals being connected by a series combination of auxiliary thyristors. Each of the auxiliary thyristors is of the type which can withstand firing resulting from excessive anode cathode potential; the sum total of the anode cathode potentials of the series-connected auxiliary thyristors being less than the anode-cathode breakdown voltages of the power thyristors. This, while a power thyristor is in a nonconductive state, an anode-cathode voltage is impressed thereacross in the forward conduction direction. At an anode-cathode voltage which is less than the breakdown voltage of the power thyristor, the auxiliary thyristors are fired so as to form a conductive path which includes the cathode-gate path of the other power thyristor, the auxiliary thyristors, and the gate-cathode path of the protected thyristor. Normal firing of the power thyristor is achieved via the auxiliary thyristors, which may be fired by light pulses or current pulses. Thus, the auxiliary thyristors perform protective and normal firing operations.

Patent DE-3280376-D1 (DE)
Inventor: AXMEAR FREDERICK EUGENE
IPC: G11B21/08
Filed: 1982-05-17
Granted: 1992-01-02
Abstract: An analog position error signal is digitised and latched. If a signal occurs on missing sector line, the output of selection circuit goes to five zero bits and error correction is prevented. The lost sector projected position, latched during the previous cycle register is truncated and rounded to an integer indicating the track type by a circuit. The select circuit also responds to the missing sector signal to select the last sector projected position from the bus. The selection circuit outputs are summed and an actual position signal is put on a bus. A circuit subtracts the last position stored from the bus position, to derive a valve representing velocity in the sector, which is latched. The velocity is then used to compute a projected location which is put onto a bus and loaded into the output register of the projected track psotion circuit. In this way, on error condition can be allowd for several sector times before the condition is reached where the next sector signal can not restore the correct actual position.
