Abstract

PURPOSE:To enable smooth connection between positive and negative trapezoidal currents, by providing a timing pulse generator which can produce a control signal of program suitable even for different specified voltages. CONSTITUTION:An AD converter 69 which outputs 00 at 6V V0, 10 at +12V, 01 at +18V, and 11 at +24V, is connected to an address terminal of an ROM65 to select either one of four control signal pulse patterns according to the output of the AD converter, and the storage capacity of the ROM65 is at least made to 4 times. One pulse per every period is generated from a clock pulse generator 61 and a counter 64 is increased to 5 bits from 4 bits. When the timing pulse pattern generator is realized with the ROM65, the switching circuit for the output can be realized with the AD converter 69.
