SYSTEM FOR CONTROLLING AN ELECTRONIC DRIVER FOR A NEBULISER

摘要

A system for controlling an electronic driver for a nebuliser or aerosol, the system comprising: an H-bridge driver for connection around a membrane to be driven; a voltage source for applying a voltage to the H-bridge driver; a feedback loop from the H-bridge to a phase shift oscillator, the output of which enters the H-bridge driver; wherein the H- bridge driver includes at least one sense resistor for detecting the phase angle between the applied voltage to the H-bridge driver and the applied current.
