Hyundai Kona: Charging System / DC/DC Converter Description and operation
Due to the considerably more frequent occurrence of starting operations, the
electrical load that occurs often leads to voltage dips in the vehicle network.
In order to stabilize the power supply for certain voltage-sensitive electrical
components, a DC/DC converter is used in conjunction with the ISG function.
The DC/DC converter supplies the relay with a voltage that also remains constant
during the starting operation.
The DC/DC converter is fitted at the behind of the glove box.
Via the test leads for input voltage and the start relay, the electronics decide
whether the power is supplied to the output via the bypass or the DC/DC converter.
In the bypass mode, the on-board supply voltage is not fed across the DC/DC
converter, but rather is transferred directly to the outputs. In the booster
phase, the vehicle voltage is adapted.

In the ISG mode, if the power of an audio system turns OFF by
drawdown while “Auto Starting” or “Idle Starting” function
operates, replace the DC/DC converter.
