DC/AC converter with intermediate rectified sinusoid with offset and PWM inversion

摘要

The electrical module (100) comprises a power source delivering signal (S-I) of a system, where the signal is a direct signal. A converter module (102) is arranged to convert supply voltage into intermediate signal (S-INT) formed of a direct component and a rectified sinusoidal component. An inverter module (103) is arranged to output signal compatible with signal (S-OUT) of another system, and that is arranged to use the intermediate signal and convert the intermediate signal into sinusoidal signal compatible with signal of another system. An independent claim is included for operating method for electrical module for adapting signal of one system to signal of another system.
