Latest Patents
One of his latest patents is the "Extended Range Regulated Power Supply." This invention provides a constant output despite extreme variations in line potential, which may exceed 50%. The power supply maintains high efficiency by operating with a first unregulated supply voltage just above the minimum voltage required by the linear regulator to maintain the desired output voltage. In cases of severe low line or drop-out conditions, a second unregulated voltage supply is connected to the input of the linear regulators to ensure a constant output voltage. Both unregulated potentials are derived from a transformer, with the second unregulated source providing the necessary voltage for the regulators to maintain the desired output under maximum line drop-out conditions. The standby unregulated potential is switched by a solid-state (FET) switch, which acts instantaneously to provide continuity of output voltage and can be configured to selectively switch in a range of standby potentials as well as a proportional pulse for modulated switching action.
Another significant patent is the "Power Converter Symmetry Correction Circuit." This invention features a pulse width modulated power converter with a single time multiplexed symmetry correction circuit. It operates to vary the pulse width of output drive pulses applied to an output transformer. As a result, the average current and the volt-second product seen by each half of the transformer primary winding remain equal under steady-state conditions. This balanced transformer drive prevents unwanted saturation of the transformer core over the entire dynamic range.
