Stepped compound voltage control circuit of battery in combination with field-control DC motor driving circuit.

摘要

Since battery is convenient for mounting up, it is widely used for various kinds of appliances, such as electro vehicles, etc. But the kind of storage, or fuel, or thermal, or solar battery has physilcal basic voltage. Generally speaking, we shall choose its voltage and capacity by means of its multiple series and supply it in accordance with the need of load by means of stepped voltage, or control it by serial linear members, or operate it by chopped wave switches. This is an efficient circuit design mainly to provide a multi-output stepped compound voltage, and further to combine with a field intensity control to enable DC motor control circuit to provide continuous linear control among stepped voltages in relation to voltage output or the output by slow increase in speed or slow feedback reduction and further to control the motor by means of series with limited current of solid switch members or constant current output.
