    摘要: A programmable decoder (201) includes a counter (204A) whose count value increases for each clock; an address decoder (205A) for converting the count value into an address; a storage (251A) storing a table defining data according to the address converted from the count value; and a latch unit (207) for latching the data according to the address output from the storage (251A). A variable driver (202) includes a plurality of MOS transistors (208), (209), (210). The latch unit (207A) has outputs connected to control electrodes of a plurality of MOS transistors (208), (209), (210). The table defines a plurality of data items in the table so that the driving force of the variable driver (202) increases with an increase of the count value. A counter (20A) updates the count value while the arm control signal is being activated.

    摘要: There has been a problem in semiconductor apparatuses of related art in which a circuit operation cannot be returned after a reverse current occurred. In one embodiment, a semiconductor apparatus includes a timer block configured to count up a count value to a predetermined value in response to a control signal being enabled, the control signal instructing a power MOS transistor to be turned on, and a protection transistor including a drain connected to a gate of the power MOS transistor, a source and a back gate connected to a source of the power MOS transistor, and an epitaxial layer in which the power MOS transistor is formed, the epitaxial layer being supplied with a power supply voltage. The protection transistor short-circuits the source and gate of the power MOS transistor in response to an output voltage of the power MOS transistor meeting a predetermined condition and the count value reaching the predetermined value. The timer block resets the count value when the output voltage of the power MOS transistor no longer meets the predetermined condition.

    摘要: This application relates to methods and apparatus for voltage balancing of voltage source converters and especially for voltage balancing of clamp capacitors of a director switch of a voltage source converter. Typically a director switch of a voltage source converter includes series connected director switch units, each having a semiconductor switching element. In some voltage source converter designs each director switch unit has an associated clamp capacitor. The method of controls involves switching the semiconductor switching elements of the director switch units to transition the director switch between conducting and non-conducting states where the timing of switching of a semiconductor switching element is based on the voltage level of the associated clamp capacitor and also the degree of any voltage imbalance between the clamp capacitors of the director switch units. A control apparatus may determine suitable switching control signals.
