[Power Amplifier Application Case] How to use a power amplifier to drive a capacitive load?

The customer requires a frequency of two hz, a square wave waveform, a high voltage of 0-1000v, and a low voltage of 0 peak-to-peak. Based on this parameter, we can select our ATA-7010 high voltage amplifier, which can amplify any waveform, has a bandwidth of DC-100KHZ, and a maximum output voltage of 2kv peak-to-peak. The gain can be adjusted in one step or 10 steps. Let's take a look at the experimental results of this test.

The power amplifier is required to have good dynamic response capability and good current driving capability. In order to make the capacitive load have better response characteristics, a discharge circuit of the capacitive load is required in the driving power amplifier. Capacitive loads place higher requirements on the power amplifier: the frequency response must meet the customer's requirements; the driving capability needs to have a certain degree of redundancy; and the circuit compensation and impedance matching design must be perfect.
