Method and system for controlling power to be fed to electrical loads
First Claim
1. A control system for controlling a power supply voltage to be fed to a plurality of electrical loads from a power supply system having an engine-driven generator and a battery chargeable by an output of the generator, the power supply voltage depending on the output of the generator, the control system comprising:
- a control unit connected to the generator and configured to;
converge the power supply voltage to a predetermined target voltage; and
when a steep change in a load current flowing through at least one specific electrical load in the electrical loads is sensed, control the output of the generator based on the sensed steep change in the load current so as to reduce variations in the power supply voltage under converging of the power supply voltage to the predetermined target voltage.

Abstract
In a control system, a control unit is connected to a generator and is configured to, when a steep change in a load current flowing through at least one specific electrical load is sensed, control the output of the generator based on the sensed steep change in the load current. This allows variations in a voltage of a power supply system to decrease while converging the voltage of the power supply system to a predetermined target voltage.
