| Zusammenfassung: | The present invention is generally directed to a control system, and, more specifically, to a control system for an electric heater.
A control system for an electric heater, e.g., an electric catalyst heater (ECH), includes a current sensor, a voltage sensor, a switching element, and a control circuit. The control circuit is coupled to the current sensor, the voltage sensor and a control terminal of the switching element and varies a control signal on the control terminal to maintain the temperature of the heating element within a predetermined temperature range. |
