High Voltage Dividers
High voltage dividers are used to scale down a high voltage for any number of reasons including: feedback for power regulation, or simplified monitoring. Potentiometric ratios as high as 1000:1 or even higher are not uncommon. Voltage divider resistors are also used in applications such as automatic defibrillators to monitor the high voltage supply used to charge the storage capacitor and switch the supply off once the required charge level is reached.
