- Figure 1. This circuit creates a 100-kHz PWM signal from a 1-kHz PWM signal to send it across an isolation transformer. The output is an integrated dc control voltage
- Figure 4. This circuit re-creates the 1-kHz PWM control signal on the isolated side. It cannot use the anticipator circuit, but R4I and C4I provide extra lowpass filtering, helping to reduce output jitter
