ABB  UBC717BE101 3BHE021887R0101  控制板主板
UBC717BE101 3BHE021887R0101主控板为驱动器的控制中枢，包括控制电源、调制脉冲的产生、控制方式及保护逻辑等四部分
电路。它接受来自面板和外控接口的信号，控制和保护射频单元的工作，同时它把驱动器运行的状态信号输到面板和外控接口。IGBT
主控板主要以高频感应加热主控制板和两个驱动为主，高频板技术采用了SG3525A作为PWM脉冲形成，UBC717BE101
3BHE021887R0101输出脉冲频率范围20KHZ—60KHZ,脉冲间隔互为180度，死区时间可以自行调整。可适用于IGBT全桥逆变串联
谐振感应加热装置用斩波器调压调功。

UBC717BE101 3BHE021887R0101 main control board is the control center of the driver, including four parts of circuits,
such as control power supply, generation of modulation pulse, control mode and protection logic. It receives signals from
the panel and the external control interface, controls and protects the work of the RF unit, and at the same time, it sends
the running state signal of the driver to the panel and the external control interface. The IGBT main control board is mainly
composed of high-frequency induction heating main control board and two drivers. The high-frequency board technology
uses SG3525A as PWM pulse, and UBC717BE101 3BHE021887R0101 output pulse frequency range is 20KHZ—60KHZ, the
pulse interval is 180 degrees, and the dead time can be adjusted by itself. It can be applied to voltage and power regulation
of chopper for IGBT full-bridge inverter series resonant induction heating device.
