FAIL-SAFE CIRCUIT FOR TAP-CHANGING TRANSFORMER REGULATING SYSTEM

FAIL-SAFE CIRCUIT FOR TAP-CHANGING TRANSFORMER REGULATING SYSTEM A tap-changing transformer system, utilized for voltage regulation of the line potential applied to a load from a source of energy, has a non-arcing switch to protect tap contacts during a tap change. A fail-safe circuit is utilized to determine that the non-arcing switch and its associated circuitry are operating properly before a movable tap contact is transferred from one stationary tap to another. In the event that the fail-safe circuit detects an improper operation of the non-arcing switch, the source is connected directly to the load to preclude the passage of any load current through the tap-changing transformer. A particular form of transfer switch useful in effecting the connection of the source directly to the load employs a current-limiting impedance arrangement.

Enhanced power converting device converting multiple dc electric power source to ac

본 발명은 복수의 DC 전원을 교류로 변환하는 개선된 전력변환장치에 관한 것으로, 특히 태양전지와 같은 직류 전원 공급원과 이로부터 생성되는 직류 전원을 PWM 제어에 의해 교류 전원으로 변환하는 DC-AC 변환기를 2개 구비하고 각각 출력되는 교류 전원 출력단과 직렬로 같이 연결된 단일 복권 변압기를 구비하여 DC-AC 변환기 양쪽의 펄스폭 제어 시작점에 임의의 시간차가 생기도록 제어함으로써 서로 더해진 교류 전압이 변압기에 전달되는 전력변환장치에 관한 것이다. 본 발명에 따르면 변조주파수를 증가시키거나 리액터의 값을 높이거나 DC-AC 변환기의 출력 전압레벨을 높이지 않고도 고주파 전류의 함량을 줄일 수 있는 효과가 있다. 또한, 변조주파수가 등가적으로 2배가 되므로 리액터의 크기를 작게 할 수 있어 리액터 내부 전력손실을 줄이는 효과가 있으며, DC-AC 변환기의 변조주파수를 반으로 낮출 수 있으므로 DC-AC 변환기 내의 도통 손실을 줄일 수 있어 전력효율이 증가하는 효과가 있다. 또한, 2대의 DC-AC 변환기를 사용하더라도 단일 복권변압기만을 사용하므로 변압기의 크기와 무게를 줄일 수 있는 효과가 있다. 태양전지, 펄스폭변조, 인버터, 변압기, 계통연계
