It's a key challenge to monitor and accurately control the power conversion from AC to DC in applications such as solar micro inverters because of safety and reliability in high voltage applications.
Actually, as you are dealing with very high, hence dangerous voltages it is critical to be able to control any ramp up and ramp down and the voltage range. it's also important to be able to monitor that effectively so you can detect any issue and shut down in case of any issue to avoid a major incident. That's the case of high voltage power supplies
So how do you manage that ?
