Heatsink Installation
When performing power conversion of several kW such as efficiency measurement based on a power supply topology, the device
power consumption itself may reach several W, which will require a heatsink. The layout allows the using of a single heatsink for the
cooling purpose even for the commutation devices. An insulator will be required under each device. The installation image is
shown in Figure 20.
