    摘要: A control circuit for a microelectromechanical element includes: a waveform generator, which is designed to generate a digital trigger signal for the microelectromechanical element, a modulator, which is designed to oversample the digital trigger signal, to subject the signal to a noise shaping, and to output the oversampled and noise-shaped digital trigger signal; and a digital driver device, which is designed to drive the microelectromechanical element using the oversampled and noise-shaped digital trigger signal.

    摘要: A switchgear control apparatus includes main contacts for first to third phases, operating mechanisms for activating the main contacts for the respective phases, voltage sensors for detecting phase voltages of a three-phase power source, and a contact closing control circuit. The contact closing control circuit first outputs a contact closing signal to the first-phase operating mechanism to close the first-phase main contact corresponding to a central leg of a core of a three-phase reactor at a first-phase voltage peak, and then a contact closing signal to the second- and third-phase operating mechanisms to simultaneously close the second- and third-phase main contacts corresponding to two outer legs of the reactor core at a zero-voltage point of the first phase three-quarter cycle later than close of the main contact for the first phase.
