converter engineering; testing miscellaneous DC power systems. SUBSTANCE: test unit that may be used as load in testing secondary power supply fed from primary DC power source has current sensor, DC converter, and storage capacitor. Newly introduced in test unit are voltage regulator, current regulator, and three control units; output power of converter is returned to primary DC circuits feeding DC power systems under test. Test unit is noted for high performance, energy conservation, and functional characteristics. EFFECT: reduced mass and size, reduced power dissipated; enhanced efficiency, enlarged functional capabilities. 1 dwg
