Reducing a drop in a residual supply-signal level on start up or restart of a power supply
In an embodiment, a method includes generating a pulse-width-modulated signal having a duty cycle, and isolating a power-supply output node in response to the duty cycle corresponding to a signal magnitude that is less than a magnitude of an output signal on the power-supply output node. For example, where a power supply has a non-zero residual output signal (e.g., output voltage) on its output node after the power supply is deactivated, a power-supply controller can use such a technique to reduce or eliminate a drop in the residual output signal caused by, or that would be caused by, a restarting of the power supply. |

Systems and methods for regulating output currents of power conversion systems
Systems and methods are provided for regulating a power conversion system. An example system controller includes a first controller terminal and a second controller terminal. The first controller terminal is configured to receive a first signal associated with an input signal for a primary winding of a power conversation system. The second controller terminal is configured to output a drive signal to a switch to affect a first current flowing through the primary winding of the power conversion system, the drive signal being associated with an on-time period, the switch being closed during the on-time period. The system controller is configured to adjust a duration of the on-time period based on at least information associated with the first signal. |

Electromagnetic actuator structure and anchoring assembly
An electromagnetic actuator assembly for moving heavy loads and running on electromagnetic energy has at least one piston providing movement of heavy loads. Two pairs of THK linear rails controls the electromagnetic actuator assembly. A pair of drive motor coil assemblies provides a force to the two pairs of THK linear rails. A foundation houses an internal tube that contains a plurality of cables. A housing mount weldment connects the plurality of cables to a pair of electrical connections of the pair of drive motor coil assemblies, and allows the plurality of cables to extend when traveling back and forth inside the internal tube. The housing mount weldment has a plurality of openings for access to the plurality of cables. An exposed linear encoder runs along the at least one piston, comprising at least one scale providing positional feedback of the at least one piston. |
