Direct current (DC) occurs when the current flows in one constant direction. It usually comes from batteries, solar cells, or from AC/DC converters. A practical dc current source provides 20 kW to a 50 Ω load and 20 kW to a Ω load. The maximum power that can drawn from it, is · kW · kW · kW. Direct current is used in any electronic device with a battery for a power source. It is also used to charge batteries, so rechargeable devices like laptops.

The DC Current Source block represents an ideal current source that is powerful enough to maintain specified current through it regardless of the voltage across the source. You specify the output current by using the Constant current parameter, which can be positive or negative. The positive direction of the current flow is indicated by the arrow. Abstract: A boost DC-DC controller built with the MAX DC-DC controller makes a simple switch-mode current source that is useful for battery charging. The voltage control loop is disabled so that the current control loop provides regulation. The DC Current Source block represents a constant current source whose output current value is independent of the voltage across its terminals. The DC Current Source block represents an ideal current source that is powerful enough to maintain specified current through it regardless of the voltage. Electrical energy sources take the form of dc voltage sources at various values, sinusoidal ac sources and polyphase sources, among others. A power electronic.
