摘要：
An apparatus for controlling power converters comprises a pulse generator (including a microcomputer (10, 11)) for supplying a pulse pattern to semiconductor devices (31-36, 51-56) of a power converter (such as an inverter (5) or a converter (3)) using the pulse width control scheme. The pulse generator is provided with a function of decimating pulses so that the pulse pattern may form a predetermined function provided that the pulse width is shorter than a limit value (Limit).
As a result, the input and output waveforms of the power converter can be made sinusoidal and can be released from the constraint of the minimum pulse width of power conversion semiconductor devices.
As a result, the input and output waveforms of the power converter can be made sinusoidal and can be released from the constraint of the minimum pulse width of power conversion semiconductor devices.
