Abstract: Electromechanical actuation systems and related operating methods are provided. A method of controlling an electromechanical actuator in response to an input command signal at an input terminal involves determining a commanded actuation state value based on a characteristic of the input command signal, generating driver command signals based on the commanded actuation state value and an actuator type associated with the electromechanical actuator, and operating driver circuitry in accordance with the driver command signals to provide output signals at output terminals coupled to the electromechanical actuator.

Abstract: A linear voltage regulator with isolated supply current is disclosed. The voltage regulator is configured and controlled such that its output current closely matches its input current (any quiescent current consumed by the regulator is negligible relative to the amount of current passed by the regulator). In certain implementations, the voltage regulator is implemented as an analog component. In other implementations, the voltage regulator includes or cooperates with digital elements, such as an analog-to-digital converter, a digital processing core, or a digital-to-analog converter.

Abstract: Embodiments are provided for dynamic management of charge. A method involves obtaining an estimated readiness time for an energy storage element, obtaining a target state of charge for the energy storage element, calculating an estimated charging time based at least in part on a difference between the target state of charge and a current state of charge, using a first charging rate to charge the energy storage element to an intermediate state of charge responsive to determining a time difference between the estimated readiness time and a first time is greater than the estimated charging time, maintaining the energy storage element at the intermediate state of charge, and responsive to determining a time difference between the estimated readiness time and a second time is less than the estimated charging time, using a second charging rate to charge the energy storage element to the target state of charge.

Abstract: A test system for measuring electrical current consumption of a device under test (DUT) includes a capacitor with power and ground terminals; a voltage regulator with input and output terminals; first and second switching elements; and a controller. The voltage regulator generates a DUT operating voltage based on its input voltage. The first switching element is arranged between a direct current (DC) voltage source and the regulator input, and the second switching element is arranged between the DC voltage source and the capacitor. The controller operates the switching elements to charge the capacitor, and to configure the test system for measuring operating current of the DUT using the capacitor as the power source.

Abstract: Embodiments are provided for dynamic management of charge. The techniques may involve obtaining an estimated readiness time for an energy storage element, obtaining a target state of charge for the energy storage element, calculating an estimated charging time based at least in part on a difference between the target state of charge and a current state of charge, using a first charging rate to charge the energy storage element to an intermediate state of charge, and responsive to determining the amount of time remaining before reaching a second estimated readiness time is less than an updated estimated charging time to charge the energy storage element at the intermediate state of charge to the target state of charge, using a second charging rate to charge the energy storage element to the target state of charge, wherein the second charging rate is greater than the first charging rate.

Abstract: A linear voltage regulator is disclosed. The voltage regulator is configured and controlled such that its output current is substantially equal to the input current. A test system for measuring electrical current consumption of a device under test (DUT) is disclosed. The test system comprises a controller coupled to a power capacitor, a voltage regulator, and a switching circuit. The controller may be configured to: control the switching circuit to place the test system into a charging state to charge the power capacitor with the DC voltage source, at a first time point, control the switching circuit to place the test system into a measurement state such that the power capacitor provides the capacitor voltage to the voltage regulator, and at a second time point after the first time point, calculate electrical current provided by the power capacitor.
