Analog PWM connection diagram using zps-101 interface

When AC and DC circuits use power transistors as switching devices, if analog control is used, it is recommended
to wire according to Figure 6-10. Use a voltage controlled oscillator to generate OCT and FCT, and RCT can be
obtained by using OCT delay "..., (either monostable or RC circuit can be used). If
voltage regulation , do not use VCT, but use the voltage generated by FCT The three-phase square waves A, B, and C form delayed
triggers and then the six three-phase square waves A+, A, B-, B, c+, and C are sent in.
For this purpose, any circuit can be used, such as the KJ009 phase-shift trigger. Use For phase-shifted control voltage,
each chip can obtain two phase-shifted pulses with a phase difference of 180°. The voltage regulation signal should be
connected through the function generator required for frequency voltage regulation for synchronous adjustment.
