DTC P0A94-588 DC / DC Converter Performance: Description

See the description of the boost converter (see DTC P0A94-442 DC / DC CONVERTER PERFORMANCE  ).

The boost converter switches the power transistors ON and OFF in accordance with the power transistor actuation signals received from the HV control ECU, in order to change the current that flows into the reactor.

Also, the boost converter regulates the duration of the switching time through PWM (Pulse Width Modulation) control, in order to control the boosting voltage.

The HV control ECU monitors the boost converter PWM circuit and detects a malfunction.
