Bidirectional Power Supply

Motor controller test benches.

Bidirectional power supply.

A wide range of nominal power voltage and current outputs are possible. Battery back up systems need bi directional dc dc converters since the batteries are charging during the time when there is an available power source but in the event of loss of power the battery now becomes the source of stand by power. Chroma 62000d bidirectional dc power supply is equipped with an active pfc 0 97 for low energy consumption and high conversion efficiency. Bidirectional dc laboratory power supplies.

When used as a load its energy recovery function can convert the absorbed dc power into ac power and return it to the grid. From research and development till end of line eol quality assurance in production bidirectional dc sources are applied. Programmable dc electronic loads conventional and regenerative series elr 10000 4u dc electronic loads with recovery function feedback into the mains 30kw. It supports both dc and ac by mounting a bidirectional dc dc converter and a bidirectional ac dc converter inside.

Bidirectional power supplies function as both a power supply unit source and an electronic load sink. Following figure is a schematic that bidirectional power supply part is represented as. Series elr 9000 hp 3u dc electronic loads with recovery. Programmable dc laboratory power supplies.

Bidirectional dc power supplies are used for testing renewable energy power systems including pv storage hybrid inverters power conversion system pcs on charging discharging and can provide battery simulation. The regenerative capacity of the devices. It m3600 regenerative power system integrates two instruments in one which is a bidirectional power supply and a regenerative electronic load. Bidirectional dc power supplies are widely spread and used in e motor and hybrid motor test benches in all stages of automobile value chain.

Psb bidirectional dc power supplies. Ea bidirectional dc programmable power supplies conventional and regenerative power supply the bidirectional dc power supply with integrated regenerative electronic load series ea psb 9000 and 10000 provides 15kw in 3u or 30kw in 4u chassis with up to 2000 vdc. A converter that can convert dc and ac bidirectionally to any power system is called a bidirectional power supply. This series easily parallels supplies for almost 2mw of power.

Operating in quadrants 1 and 4 each bidirectional power supply is user programmable to source or sink current from a device under test. Moreover to fit the universal ac power input range the 62000d series has a very wide input power range of three phase 200vac to 220vac and 380vac to 480vac inputs.
