Patent Number Title Of Patent Date Issued
4713743 Load-commutated inverter and synchronous motor drive embodying the same December 15, 1987
In a load commutated inverter system, the recovery time of the outgoing static switch is extended by applying an auxiliary commutation voltage in series with the associated phase line. This action is triggered in response to the gating signal of the on-coming switch during a time int
4672288 Torque controller for an AC motor drive and AC motor drive embodying the same June 9, 1987
In an induction motor drive a signal representative of the torque T as derived by sensing only the stator armature current I, and the slip frequency f.sub.2 and by calculating instantaneously T=I.sub.1.sup.2 F, where F is a function of f.sub.2 /R.sub.2, where R.sub.2 is the rotor res
4644248 Line fault tolerant synchronous timing reference generator for static VAR generators February 17, 1987
A timing reference generator for producing a multi-phase timing reference signal in synchronism with a multi-phase source voltage signal is disclosed. The timing reference generator uses an N stage array of series connected phase-locked loop (PLL) circuits to preserve the prefault co
