    • An inverter circuit including an inverter driving circuit and a plurality of pairs of switching elements coupled to a DC power source. The inverter driving circuit includes first and second gate driving circuits. The first gate driving circuit with a pulse transformer is coupled to a first switching element of each pair of switching elements, the latter of which is coupled to the positive side of the DC power source. The second gate driving circuit uses a non-induction control device, and is coupled to a second switching element of each pair of switching elements, the latter of which is coupled to the negative side of the DC power source. The total number of power sources required for the inverter driving circuit can be greatly decreased by using first gate driving circuits requiring no power source, as compared with that of a conventional inverter driving circuit constituted only by second gate driving circuits. A faster response speed for preventing damage to switching elements can be achieved by using second gate driving circuits having a fast response speed, as compared with that of a conventional inverter driving circuit constituted only by first gate driving circuits. Further, even if chopping is conducted, a high inverter efficiency can be obtained.
    • 一种逆变器电路,包括反相器驱动电路和耦合到DC电源的多对开关元件对。 逆变器驱动电路包括第一和第二栅极驱动电路。 具有脉冲变压器的第一栅极驱动电路耦合到每对开关元件的第一开关元件,后者耦合到直流电源的正侧。 第二栅极驱动电路使用非感应控制装置,并且耦合到每对开关元件的第二开关元件,后者耦合到直流电源的负极侧。 与仅由第二栅极驱动电路构成的现有的逆变器驱动电路相比,通过使用不需要电源的第一栅极驱动电路,可以大大降低逆变器驱动电路所需的电源的总数。 与仅由第一栅极驱动电路构成的常规的逆变器驱动电路相比,通过使用具有快速响应速度的第二栅极驱动电路,可以实现用于防止开关元件损坏的更快的响应速度。 此外,即使进行斩波,也可以获得高的逆变器效率。
