Title: Voltage setter
Inventor: ONODERA HARUKI
IPC: H02P29/02
Filed: 1990-04-04
Abstract: PURPOSE:To realize a voltage setter which rapidly detect a malfunction even if the malfunction occurs in a constant-voltage source circuit and obtain stable output characteristic by deciding whether the output side voltage of a variable resistor falls within a predetermined valid range or not. CONSTITUTION:A contact 8 of a switch 7 is closed, a comparator 12 reads an input voltage 1, decides whether it falls within a predetermined valid range or not, and it is added by a calculator 13 if it falls within the range. If it is decided to be out of the range, the number of the input voltages is counted. Whether this value is less than the total number (n) of the input voltages or not is decided, and if it is less than that, the voltage 1 is switched to an input voltage 2 by a switching circuit 15. If both are out of the range, i.e., if the counted value becomes 2, a switching discriminator 14 sends a command to a calculator 13, holds the previous value, and continuously outputs it as a speed command.
