Title:
METHOD AND DEVICE FOR CONTROLLING n ELECTRIC LOADS IN CIRCUIT DEVICE
Document Type and Number:
Japanese Patent JP2004213658
Kind Code:
A
Abstract:
To realize optimized design regarding electromagnetic compatibility (EMV) of a device for controlling at least two electric driving parts.
In a method, n pulse width modulation signals are generated by being shifted in time for control of n electric loads and consequently, an effective value of current IL flowing to the n electric loads in conducting wire is reduced. In a device, a microcontroller for generating a control signal has first and second output sides and first and second control lines are connected with the first and second output sides for the control of n power semiconductor constitution element of the n electric loads.
