PWM SIGNAL GENERATOR, AND INVERTER EQUIPPED WITH THIS PWM SIGNAL GENERATOR |
摘要 |
The PWM signal generator of the present invention generates a first pulse waveform in which a first on-time ”T 1 calculated by a first on-time calculator (401) is used as an on-duration, and a second pulse waveform in which a second on-time ”T 2 , calculated by a second on-time calculator (402) when a preset delay time has elapsed from the start of the calculation of the first on-time ”T 1 , is used as an on-duration. Also, a PWM signal generator (413) generates a PWM signal on the basis of a composite pulse in which the generated first pulse waveform and second pulse waveform are combined, and the first on-time calculator (401) calculates the first on-time ”T 1 at the end of the composite pulse waveform. |
