Hi,
I am doing a project in which i need to power piezo transducer with 140 kHz ~20V signal. When I`m powering piezo with generator it only takes 6mA. But when I try to power piezo with my circuit it takes more than 1A. When i place resistor it gets hot and circuit lose power. Where is the problem?
Maybe you could give me advice of alternate ways to power piezo with such a signal?
