在PSCAD环境下，采用双闭环控制的正弦脉宽调制整流器，直流侧控制效果较好。-In the PSCAD environment, using sinusoidal PWM rectifier dual closed loop control of DC side, better control effect.

this is source code for water sensor detector. It generates PWM signal as transmitter through water then converted by rectifier to be digital input. by: ridwan
