    Diode CL04-12 110v 60HZ inverter

    This is for DIY connecting a 110v 60HZ solard inverter from 12v DC battery to 110v AC 60HZ output. Using a CL04-12 Microwave diode that I already own. I want to know if this diode is right for this. I want to protect my inverter while I use the electric power from electrical power Co. And what...

    Could somebody please help me understand this circuit?

    Could someone please explain to me what this circuit is used for? I believe it is a full wave bridge rectifier but I'm unsure as to what the zener diode is used for in this arrangement? Thanks in advance

    Stop Dc back feeding into Ac supply

    How can I and where should I install in circuit a diode? Diodes? Or any other device that could stop DC short to chassis on my RV from back feeding when i plug my 120 volt 20 amp system into RV which is causing havoc in damage to the A/C gfci breakers frying them constantly ? Also this will...

    AC / DC voltage drops across Diode

    I am unable to find voltage drop of normal silicon diode(0.7v) on Voltmeters during Proteus Simulation. Also we consider 0.7v drop of diode equivalent to DC Source of 0.7v but DC voltmeter is not showing any output and AC Voltmeter shows around 5 volts drop across diode instead of 0.7V.Kindly...

    Blocking diode for radiator pump?

    Hi I have a central heating system installed but the controller cannot differentiate between hot water demand and central heating demand. Currently when hot water demand is on and CH is off the CH (radiator) pump has to be run. The issue is that the boiler only has one input for heat demand so...

    Wiring an add on DRL to vehicle - relay use and diode?

    Hi My daughter wants to add some DRLs to her car. The wiring diagram attached is being followed. I had heard that relays require a diode across the coil so I have shown one in the illustration (see grey line work). Is a diode actually required in this application or not? Thanks DRL = daytime...

    Diode advice

    I currently have an intermittent issue with a disabled alarm system. The pullcord has a fault monitor connected across it in the form of a resistor and diode in series which I suspect is the culprit. The diode only reads continuity one way as expected but the resistance through it the correct...

    Is there a danger with relays without diodes

    I came across this LINK on Wikipedia the other day, since then I’ve done some googling and found out this is a known fact that if relay hasn’t got a diode fitted, this might/will cause a spike and might damage something on the Elise S1 circuit. I copy~pasted this form google "Since an...
