students which will take college level every year. However in the trainer kit procurement as a learning tool have problems due to the limited number of trainer kit. Especially in Power Electronics lessons that still lacks of trainer kit for practice. Buck-Boost converter is a circuit with the input of DC voltage and generate output voltages with opposite polarity to the input (negative polarity). The generated negative voltage output can be set larger and smaller than the input. In this thesis the author designed a buck boost converter trainer kit which uses 12 VDC input, frequency of 10KHz, and using a duty cycle with a range of 20% to 80%. The voltage generated by using a duty cycle of 20% is -2.12 VDC and currents 0.21 A with 74.2% efficiency, while 80% duty cycle generates a voltage of -8.46 VDC and currents 0.08 A with 11.05% efficiency. At the moment of 80% duty cycle and the generated voltage is not greater than the input, this is due to the selection of L and C values which is less efficient.
