QUICK START GUIDE

THERMAL CONSIDERATIONS

The EPC9509 demonstration system showcases the EPC2108 and

EPC2036 eGaN FETs in a wireless energy transfer application. Although

the electrical performance surpasses that of traditional silicon devices,

their relatively smaller size does magnify the thermal management

requirements. The operator must observe the temperature of the gate

driver and eGaN FETs to ensure that both are operating within the thermal

limits as per the datasheets.

NOTE. The EPC9509 demonstration system has limited current protection only when

operating off the Pre-Regulator. When bypassing the pre-regulator there is no current

protection on board and care must be exercised not to over-current or over-temperature

the devices. Excessively wide coil coupling and load range variations can lead to increased

losses in the devices.

Pre-Cautions

The EPC9509 demonstration system has a limited controller and no

enhanced protection systems and therefore should be operated with

caution. Some specific precautions are:

1. Please contact EPC at [email protected] should the tuning of the coil be

required to change to suit specific conditions so that it can be correctly

adjusted for use with the ZVS class-D amplifier.

2. There is no heat-sink on the devices and during experimental

evaluation it is possible present conditions to the amplifier that may

cause the devices to overheat. Always check operating conditions and

monitor the temperature of the EPC devices using an IR camera.

3. Never connect the EPC9509 amplifier board into your VNA in an

attempt to measure the output impedance of the amplifier. Doing so

will severely damage the VNA.
