Abstract

PURPOSE:To simplify the computation of an average value of load current necessary to control the chopper current by a method wherein a means to compute an output pulse of voltage frequency changer is adopted as a means to digitize a chopper load current. CONSTITUTION:An output current of a chopper is detected by a current detector 16, the detected output is converted into a pulse of an appointed frequency by a voltage frequency changer 18 and is fed to a microcomputer 20 previously inputed with a command current value is. In the computer 20, the output pulse is computed by a counter with a cycle an integer times of the on-off cycle of the chopper, the counted value is compared with the command current value to the chopper and an on-off command is sent out to the chopper. By this way, an average value of load current of chopper can be computed simply and securely in a short time.
