电梯故障监测保护器已成为电梯不可缺少的配套装置，电源系统是保护器的关键。将具有脉宽调制功能的单片机及开关方式的脉宽调制控制技术和井森式开关逆变电路用于电源系统，使之与软件编程结合在一起，这样的电源系统灵活性更大，适应性更强。
The elevator fault monitoring protector has become an indispensable supporting device for the elevator, and the power system is the key to the protector. The pulse width modulation function of single-chip microcomputer and switch mode pulse width modulation control technology and Jingsen switch inverter circuit are used in the power supply system, so that it is combined with software programming. Such a power supply system has greater flexibility and adaptability. Strong.
