Page 20: Limitations And Protections
Example: A CSA96 providing 20A at 200Vpp with a sinus waveform (1kVA) to an ideal inductor consumes less than 40W due only to the power components losses of the amplifier. If the inductor is non-ideal, the amplifier will also deliver the active power (RI²). This active power cannot be higher than the maximum power of the power supply (600W). -
Page 21: Buffer Capacitor Extension
In this case, it may be smarter to add a buffer capacitor extension rather than a rheostat since it may be smaller and more efficient. Ask Cedrat Technologies if the calculated energy needed is larger than may be smaller and more efficient.
