Two-levels inverter with half bridge matrix converter and low frequency output

摘要

The two levels inverter with half bridge matrix inverter and low frequency output consist of DC power supply (1), that feeds high frequency inverter (2) with the centre out. The voltage from the high-frequency inverter (2) with the centre out is fed from terminals (V1) and (V2) to the half-bridge matrix inverter (3) and central outlet (VO) of high-frequency inverter (2) is connected to the one pole of the load (4). The second load pole (4) is connected to the central outlet of half-bridge matrix inverter (3). The half-bridge matrix inverter (3), that modifies high-frequency voltage from high-frequency inverter (2) to voltage with lower frequency necessary for the load (4), consisting of 2 way switches (6) and (7). Correct operation of the entire system provides control pulses from the control circuit (5).
