    Components
    PSU 1 power supply unit, capable of supplying maximum pulse voltage required (maximum of voltage range + X design voltage) with pulse current demanded by invertor at this voltage with 2 % regulation (no load to full load).
    PSU 2 power supply unit adjusted to maximum of input voltage range.
    NOTE 1 Preferably both PSUs should be fitted with current limits to prevent damage in the event of the invertor under test breaking down.
    TH 1 main switching thyristor used to apply voltage pulse to the invertor. Many common thyristors should be suitable for this job. They shall have a turn-on time of about 1 ms and adequate pulse current capability.
    TH 2 thyristor controlling the action of the relay RLC.
    D 1 reverse current by-pass diode for TH 1 . Allows initial oscillatory transients to operate. Shall be fast type (200 ns to 500 ns) with voltage rating equal to twice the maximum pulse voltage.
    D 2 blocking diode for PSU 2 . Prevents output impedance of PSU 2 , loading voltage pulse source (PSU 1 ). Shall be fast type (approximately 1 ms turn off) with voltage rating equal to twice the maximum pulse voltage.
    RLC pulse termination relay with contacts K.
    R and C spark suppression components.
    Suggested values are 1 00 W and 0,1 mF (for 26 V invertors).
    S 1 switch used as ON/OFF or reset control.
    NOTE 2 The delay system for securing the correct duration of the pulse is not represented on the figure. It shall ensure the triggering of thyristor TH 2 500 ms after the action of TH 1 , account being taken of the operating time of the relay.
