<P>PROBLEM TO BE SOLVED: To provide a voltage generator capable of generating a PWM signal easily to generate a target voltage. <P>SOLUTION: A voltage generator comprises: a CPU 3 that acquires a duty ratio corresponding to an output voltage value from a programmed voltage table to generate and output transmitted data including the duty ratio; a UART transmitter 7 that includes a buffer which stores accepted transmitted data, retrieves the stored transmitted data in order of storing and transmits the retrieved data as PWM signal in series, and a transmission request part which requests the CPU 3 to transmit the transmitted data when all the transmitted data are retrieved from the buffer; a cumulative voltage generation part 15 that generates the average voltage from the PWM signal; an amplifier 11 that amplifies the average voltage to generate an output voltage; and an output control part 17 that generates a control signal based on the output signal to control output/halt of the output voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
