Abstract：Objective In order to evaluate the anti-disturbance performance of ventricular assist devices, we propose a high-power instantaneous
energy (magnetic field, electric field) anti-disturbance test platform. Methods For high frequency magnetic field, high power variable voltage
design and high frequency coil manufacturing technology were used to design and fabricate resonant circuit. Combining signal source and
high-speed bipolar power supply, a test platform for electromagnetic disturbance immunity was built. The interference frequency generated
by high frequency magnetic field could cover the typical working frequency range of high frequency electric knife, and reduced the
requirement of output power index of high-speed bipolar power supply. For high frequency electric field, coupling coil was used to realize high
frequency boost. Results The measured data showed that the test platform could generate a high frequency magnetic field up to 2598 A/m
in the range of 100 kHz to 1000 kHz. It could generate a boost gain of up to 402.9 times and achieve a high-frequency voltage of up to 5000 V.
It could effectively evaluate the anti-disturbance performance of the tested products to the high-frequency electric field. Conclusion The
testing platform can be used to test the anti-interference of high frequency magnetic field, high frequency electric field and high frequency
conduction current, respectively, which is helpful to evaluate the anti-interference performance of ventricular assist device to the high
frequency and high power disturbance scientifically and effectively, and to form a reasonable criterion for evaluating the electromagnetic
compatibility quality of ventricular assist devices.
