Method and circuit arrangement for controlling a load

Device for control and discharge control of an electrical load comprising:

• at least two point loads by means of a control unit, which uses a driver stage to drive a current into the electrical load, wherein the control unit controls switching cycles for the electrical load,
• wherein each switching cycle comprises a control frame and a discharge frame, a controllable switch is connected in parallel to each point load so that each point load can be switched in the switching cycle independently of the other point load, and
• wherein the controllable switches are configured to switch on the point loads during a control frame, and the controllable switches are configured to switch off the point loads during the discharge frame, and
• wherein a capacitor is in parallel to the electrical load and a discharge resistor with an additional controllable switch is arranged in parallel to the capacitor, wherein
• the discharge resistor discharges the capacitor to ground or to zero point or another voltage potential when the controllable switch is closed, or a discharge resistor with a controllable switch connected downstream of it embodies a connection between the input capacitor and the capacitor and the discharge resistor discharges the capacitor into the input capacitor when the controllable switch is closed, or a discharge inductor with a controllable switch connected upstream of it embodies a connection between an input capacitor and the capacitor and discharges the capacitor into the discharge inductor and input capacitor when the controllable switch is closed.
