    摘要: An improvement over prior art voltage timing compensation circuits is achieved by incorporating a function generator to provide a more accurate non-linear compensation to pulse timing delay, which is typically a non-linear function of voltage. An improvement over prior art temperature timing compensation circuits is achieved by providing for actual temperature measurements to be made and used to drive the timing compensation circuitry for a more accurate temperature timing compensation than provided by prior art temperature synthesis, while still using a relatively simple compensating circuit. In some embodiments a timing compensation circuit combines both voltage and temperature timing compensation.

    摘要: A high voltage pulse generator utilizes an even number of Marx cells using L-C inversion topology. Each Marx cell is associated with an individual inverter transformer having a primary winding connected to the output of an ac power supply such as a series resonant inverter. The secondary of each inverter transformer is half-wave rectified to charge the energy storage capacitors in each Marx cell. A distributed voltage sensing scheme can be provided for accurate feedback to the inverter's controller. An inductive element can be used to achieve a magnetic diode effect in the L-C inversion circuit to reduce component stress and improve efficiency. A transformer-coupled floating gate drive circuit is used to provide local power conditioning and trigger timing for discharge of the energy storage capacitors.

    摘要: The magnitude and wave shape of instantaneous alternating current and power delivered from a converter's single phase alternating current output is controlled by a closed loop power control scheme independent of the direct current input voltage to the converter. A fast averaging methodology for the value of control magnitude and wave shape of the instantaneous power delivered from the alternating current output can be used in the closed loop power control scheme to limit the magnitude of delivered power. The closed loop power control scheme can be used in both power grid-tied applications and stand-alone non-powered load line applications.

    摘要: The magnitude and wave shape of instantaneous power draw from a single phase alternating current power source to a power converter is controlled by a closed loop power control scheme independent of the direct current output voltage of the converter. A fast averaging methodology for the value of control magnitude and wave shape of the instantaneous power draw by the converter from the alternating current source can be used in the closed loop power control scheme to limit the magnitude of power draw.
