    摘要: Systems and methods for electrical power conversion include the provision of a full-bridge tunnel diode inverter topology which provides a balanced push-pull drive voltage and current across the entire transformer primary. Moreover, the full-bridge tunnel diode inverter may avoid operating its tunnel diodes in a high-current/high-voltage state at light loads, unlike a single-diode inverter. The disclosed principles also allow a full-bridge tunnel diode inverter topology that may avoid RF chirps in the tunnel diodes during rising or falling device ramp currents since the primary current passes through two tunnel diodes in series.

    摘要: For controlling the rotational speed of an induction motor (3), a pulse-width modulated inverter (2) is provided which converts direct current to alternating current, the converted current being fed to the motor (3). The output voltage and frequency of the inverter (2) is controlled in relation to the motor speed by changing the number of pulses in a half-cycle of the inverter output voltage in accordance with the DC supply voltage and/or with the motor current and/or in accordance with electrical fluctuations which are disturbances in a controlling system for the inverter output voltage.
