摘要： An apparatus (e.g., 12) for interrupting an electrical current between two contacts includes a first contact (12) and a second contact (16). The first and second contacts are separable away from one another to interrupt an electrical current flowing between the contacts. An arc constrictive zone (20) may be disposed around the contacts confining an arc (32) generated between the contacts during a separation of the contacts. An ablative material (28) may be disposed in the arc restrictive zone to be ablated by the arc to form a vapor for cooling the arc and producing an increased pressure in the restrictive zone responsive to the arc to force separation of the contacts.

摘要： An ac-ac power converter system is provided for supplying power to an electrical load. The ac-ac power converter system provides an output voltage having variable amplitude and/or frequency. The ac-ac power converter system includes a boost inductor for applying a discontinuous current to an ac-ac power converter. The ac-ac power converter includes a rectifier circuit comprising of a first set of gate controllable active switches for converting an input ac power to a dc power and an inverter circuit comprising of a second set of gate controllable active switches for converting the dc power to an output ac power. In addition, the ac-ac power converter system includes a switch for switching between a first mode of operation and a second mode of operation. The first set of gate controllable active switches is common between the inverter circuit and the rectifier circuit and is operable at about 50 percent of duty cycle in the first mode of operation while the inverter circuit is a half bridge inverter circuit in the second mode of operation.
