ZCC是什么意思

In this paper, some problems about IGBT's operation characteristics are discussed. A driving mode called zero voltage commutation and zero current commutation ( ZVC/ ZCC) technique with high efficiency and safety is introduced.

对IGBT的工作特性及存在的问题进行了深入探讨，详细介绍了用于提高大功率IGBT电桥的开关效率和安全性的ZVC／ZCC驱动模式。

The high frequency switch technology of large power is developed successfully by the perfect control of PWM ( Pulse Width Modulation) and ZCC ( Zero Current Control), ZVC ( Zero Voltage Control) in the unit.

通过PWM（脉宽调制）和ZCC（零电流控制）、ZVC（零电压控制）的完整控制，成功开发应用了大功率高频开关技术。

Conclusion: ZCC could inhibit the remodeling of airway in chronic asthma by way of reducing the precipitation of collagen and Fn, thus help the prevention and treatment of chronic bronchial asthma.

结论：止喘胶囊（补肾健脾法）可能通过减少气道壁胶原和Fn沉积，抑制慢性哮喘的气道重建，有利于对慢性哮喘的治疗和预防。
