9.5.1. Overview

The Low Voltage DCDC converter Voltage Setpoint Manager (LvDcdcHvCurMgr) is responsible for managing the voltage setpoint of the low voltage DCDC converter based on the current drawn from the high voltage system. It aggregates the input currents from multiple DCDC converters and calculates the total current drawn. The component also provides the minimum required power from the high voltage system for normal operation of the low voltage power system.

9.5.2. Functions

Title

Description

1

Aggregate DCDC Input Currents

Aggregates the input currents from multiple DCDC converters (DCDC1, DCDC2, DCDC3) to calculate the total current drawn from the high voltage system. If any of the input current signals are invalid, the previous valid value is used.

2

Provide Minimum Required HV Power

Provides the minimum required power from the high voltage system for normal operation of the low voltage power system. This value is configurable via the parameter LvdhvcmLvPwrCnsMin.
