摘要： A semi-controllable device driving method and apparatus and a hybrid device of the present disclosure belong to the electrical field, and are particularly a driving method, with no driving dead zone or with an extremely small driving dead zone, that is applicable to a semi-controllable device such as a thyristor; a semi-controllable driving apparatus, with no conduction dead zone or with an extremely small conduction dead zone, that is applicable to a driving loop of a semi-controllable device such as a thyristor; and a hybrid device with no conduction dead zone or with an extremely small conduction dead zone. In the semi-controllable device driving method, a voltage detection switch is used; an input end of the voltage detection switch is connected to two ends of a semi-controllable device that needs to be driven; the voltage detection switch is connected, in series, in a driving loop of the semi-controllable device; the voltage detection switch is turned on when a potential difference at the two ends of the semi-controllable device is not greater than an on-state voltage of the semi-controllable device; and the voltage detection switch is turned off after detecting that the semi-controllable device is turned on. The present disclosure has an advantage of no driving dead zone or an extremely small driving dead zone.

摘要： A control arrangement and method is provided for a power electronic system configured as a high-speed source-transfer switching systems (HSSTSS). The HSSTSS supplies an electrical load with alternating current from either a first source or a second source via respective first and second solid-state switches. The HSSTSS also includes a controller that samples the voltage waveforms of each of the first and second sources to detect when transfer between the sources is desirable, e.g. outages or voltage that is either too low or too high. The controller provides appropriate control signals to control operation of the solid-state switches and transfer supply of the load therebetween. The control arrangement avoids undesirable current flow between sources via a comparison of the voltages of the sources and current in the outgoing source, i.e. a polarity comparison to ensure that the current that will flow in the incoming source after transfer will be in opposition to the current flowing in the outgoing source before transfer. Thus, the transfer is delayed until the polarity comparison is satisfied. Additionally, the control arrangement minimizes undesirable transfer delays by establishing appropriate transfer conditions before issuing control signals to perform the transfer between sources, i.e. the transfer to turn on the incoming switch is delayed until after appropriate conditions establish that the outgoing source is off or can be effectively turned off. One form of appropriate conditions include the establishing of forced commutation conditions, preferably established by the incoming source voltage differential and the outgoing current being of the same polarity such that the voltage differential across the solid-state switch that is being turned on is sufficient to establish an initial change in current flow in opposition to the current flow in the solid-state switch to be turned off. The appropriate forced commutation is established by the voltage differential between the two sources being of sufficient magnitude to force the outgoing current to zero. Additionally, under certain conditions, the transfer is accomplished by awaiting the next current zero.
