A switching mode DC-DC converter applying the Integrated-Voltage-Control method works stably and has no steady state error. The basic circuit of this converter consists of an error voltage integrator and a hysteresis comparator which drives a power transistor to on/off. The DC-DC converter circuit can be extended to a Four-Quadrant DC-DC converter circuit. This Four-Quadrant converter has four hysteresis comparators driven in parallel by an error voltage integrator, and each comparator drives a prearranged power transistor engaged with one of the four quadrants of the converter operation on the voltage-current plane.<br>In this paper, we propose a new NPC (Neutral-Point-Clamped) Multi-Level Four-Quadrant DC-DC converter applying the Integrated-Voltage-Control method, developed from the Four-Quadrant DC-DC converter driving circuit. This new NPC converter consists of eight hysteresis comparators driven in parallel by an error voltage integrator. There are eight operating regions in this new converter and one of eight power transistors is driven by one of eight hysteresis comparators to on/off in each prearranged region. The neutral-point voltage can be kept at a constant value by a new restrain control scheme also proposed in this paper.<br>It has been confirmed experimentally that the new NPC converter has no short circuit mode, no steady state error, and a quick response time.
