Latest Patents

Lucas's latest patents include the "Power Supply Start Up Circuit" and the "Efficient Battery Transfer Circuit." The Power Supply Start Up Circuit provides a secondary output voltage from an input voltage. This circuit includes power supply circuitry for creating an unregulated DC bus voltage line and a regulator circuit connected to the DC bus voltage line for controlling a first switch in series with a transformer winding. The control circuit samples an output voltage to manage the output voltage by cycling the first switch. Additionally, the circuit features a pulse generator circuit connected to the regulator circuit for controlling start and stop cycles of the regulator circuit, along with a comparator circuit for monitoring the secondary output voltage and disabling the pulse generator circuit during normal operation.

The Efficient Battery Transfer Circuit is designed to connect to a load and a power supply, ensuring that the load receives at least a minimum supply voltage during normal operating conditions. This circuit also includes a source of battery voltage for powering the load during a power failure when the power supply cannot maintain the minimum supply voltage. The battery transfer circuit comprises a first circuit for applying the minimum supply voltage to the load during normal conditions and a second circuit for charging the battery to an optimal voltage greater than the minimum supply voltage. This second circuit down-regulates the optimal charge voltage to a predetermined voltage, which is applied to the load during a power failure.
