    摘要: A thyristor switch (1) is constituted of a pair of arms connected in anti-parallel, each of the arms including a plurality of thyristors connected in series. A controller (4) includes a phase detecting unit (10) configured to detect a phase of a power supply voltage supplied from an alternating-current power supply (2), and a gate signal generating unit (20) configured to interrupt a gate signal when an open command is provided to the static switch and the phase of the power supply voltage detected by the phase detecting unit (10) matches a target phase. The target phase is set outside of a phase range where interruption of the gate signal is prohibited, the phase range being set so as to include a zero crossing point at which a load current is switched in polarity.

    摘要: A power supply control system is proposed for controlling the supply of power from an alternating current (AC) power source to a load. A triac (T1) in series with the load is controlled by a controller (11), typically an MCU, coupled to the gate terminal of the triac via a rectifier unit comprising at least one rectifier (B1). The rectifier unit transmits a control signal from the controller to the triac, and additionally generates a power signal for powering the controller. Thus, advantageously, a common path can be used for triggering the triac, and powering the controller, so that no sophisticated power supply is required for the controller. This both reduces cost and increase reliability. A capacitive network (ZL, ZH) is provided in parallel with the triac, and electrically connected to an input of the rectifier unit. Optionally, the triac may be additionally triggered in the case of a power surge superimposed on the AC power source, to divert the power surge away from vulnerable components.

    摘要: A static transfer switch is used for switching an output load from a first power source to a second power source. A first switching unit has a first pair of silicon controlled rectifiers (SCR). A second switching unit has a second pair of SCRs arranged in an anti-parallel configuration. The control circuit determines whether at least one of the SCRs is activated in accordance with the voltage between the gate and the cathode of the at least one SCR. If the voltage between the gate in the cathode is at least 150 mV, the control circuit indicates that the at least one of the SCR is activated.
