PWM with AT90S8515 a good practice to understand the logic can give 200w Power should be developed for more
The driver circuit method used in section H-Bridge driver integrated HIP4080 I have in the market
The schema of the latter and ‘very simple, despite the Difficulties’ linked to power and it’s not particularly interesting because of the microprocessor controller (PIC).
I wanted than to make something similar but with reduced power to 220V 200W max. I state that my purpose and ‘only experimental, there are, of course, how best to developer a circuit like that.
The diagram and ‘a bit’ more complex than that Article, ’cause using the circuit configuration of power MOSFETs in H-Bridge’ with its driver which in my opinion ‘more’ efficient management instead and ‘Entrusted to a AT90S8515 microcontroller which reads and displays, among other things, the various parameters Involved (voltages, currents etc.

Gas Detector Circuit ATtiny45
Gas sensors are employed in a wide range of applications in the fields of safety, health, instrumentation etc… Common examples are domestic/commercial alarms for explosive or toxic gases or in automotive application, as gas leakage detectors for LPG powered cars and exhausts detectors inside any fuel-powered truck/car. Such sensors, nowadays, are found also in applications involving air quality control systems and pollution monitoring.
Today’s sensors, while featuring an high sensitivity to a wide gases variety, are very compact in size and have significantly reduced their power consumption to better adapt to portable solutions.
Building a system with a gas sensor is not as easy as it could appear. Despite the sensor could be treated basically as a variable resistor (which value depends on gas concentration in air) the practical implementation in a project should be done considering some design rules, especially if the final circuit is a device to be used in a field where reliability is strongly required (e.g. safety).

PWM mit AT90S8515 eine gute Praxis zu verstehen, die Logik kann 200w Power sollte für mehr entwickelt werden
Die Treiberschaltung Methode verwendet in Abschnitt H-Bridge-Treiber integriert HIP4080 Ich habe auf dem Markt
Das Schema der letzteren und “sehr einfach, trotz der Schwierigkeiten” mit der Macht verbunden und es ist nicht besonders interessant wegen der Mikroprozessor-Controller (PIC).
Ich wollte aber etwas ähnliches machen, aber mit reduzierter Leistung bis 220V 200W max. Ich behaupte, dass mein Ziel und “nur experimentell, gibt es natürlich, wie am besten eine solche Entwickler zu entwickeln.
