Features of regenerative inverter
	Improvement in safety through restrained speed control and stable operation in heavy-grade territory Improvement in stop accuracy of fixed points through steady electric braking Reduction of brake shoe wear through reduction in air brake applying frequency Prevention of temperature rise inside the tunnel of subway
	The regenerated power is transformed into AC power instead of being consumed as heat loss.
	The regenerated power is transformed into AC power and utilized in the supplementary equipment such as high distribution load, etc. to promote the reduction in power consumption of the entire electric railways equipment.
	The cross connection of inverter and rectifier using the circulating current system allows continuous switching of inverter-rectifier, ensuring stable operation against variable load.
	Equipped with a voltage control loop, the inverter unit responds quickly to any sharp change in regeneration, preventing the rise in trolley voltage.
	Because of the externally commutated phase control system using power commutation, the control operation is simple, and with a large number of operating records the device ensures high reliability.
